1      General

1.1   Introduction

Congratulations on your purchase of the Maretron Current Loop Monitor (CLM100). Maretron has designed and built your monitor to the highest standards for years of reliable, dependable, and accurate service.

 

Maretron’s CLM100 converts commercially available 4-20mA transducers into digital data so a wide variety of information can be displayed on compatible NMEA 2000® displays. Numerous 4-20mA transducers are supported by the CLM100 including transducers for monitoring DC voltage and current, flow rate, distance, linear velocity and acceleration, angle, angular velocity and acceleration, temperature, humidity, resistance, strain gauges, force (load cell), pressure, decibels, and rotational rate. Some typical applications where the CLM100 is used together with a commercial available 4-20mA transducer include machinery monitoring using accelerometers and vibration sensors. Vibration monitoring of pumps, motors, fans, compressors, and gear boxes provides an early warning of potential problems resulting fewer breakdowns and reduced maintenance expenses. Another application example using the CLM100 is shaft speed monitoring. A commercially available 4-20mA rotational rate sensors is coupled to the shaft of interest and the CLM100 converts the transducer to an RPM that can be read on by a compatible NMEA 2000® display. And if you’re concerned about the force exerted on a mast stay or perhaps a vessel tow attachment point, commercially available clevis pins with 4-20mA interface can be connected to the CLM100 and the corresponding load monitored using any of Maretron’s display products.

 

The Maretron CLM100 is designed to operate within the harsh demands of the marine environment.  However, no piece of marine electronic equipment can function properly unless installed, calibrated, and maintained in the correct manner.  Please read carefully and follow these instructions for installation, calibration, and usage of the Maretron CLM100 in order to ensure optimal performance.

WARNING

 

Maretron pressure transducers are not approved for use with gasoline. If you wish to use the CLM100 to monitor pressures of gasoline, you must obtain a pressure transducer that is approved for use with gasoline.

 

For other parameters, Maretron does not offer any accessories for the CLM100; however, the CLM100 is compatible with any transducer which offers an industry standard 4-20mA current loop interface and is able to operate with a current loop excitation voltage of 12-15VDC.

 

1.5   Quick Install

Installing the Maretron CLM100 involves the following steps. Please refer to the individual sections for additional details.

 

1.    Unpack the Box (Section 3.1)

2.    Choose a Mounting Location (Section 3.2)

3.    Mount the CLM100 (Section 3.3)

4.    Connect the CLM100 (Section 3.4)

5.    Configure or Program  Each Channel (Section 4.1)

 

1.6   Theory of Operation

The CLM100 operates by measuring the current transmitted by 4-20mA current loop transducers. The current reading is translated to a parameter value according to the channel’s operating mode as well as the 4mA and 20mA parameter calibration values.

 

The CLM100 can be used with either 2-wire or 4-wire 4-20mA current loop transducers.

 

Standard NMEA 2000 messages are used for parameters wherever possible. Proprietary messages are used for other parameters.

1.7      Resolution

The CLM100 can measure parameters with a resolution of approximately 0.33% of full scale.

 

In many cases, the resolution to which the CLM100 can measure a parameter may be lower than the resolution at which NMEA 2000 represents the parameter. As an example, if a channel of the CLM100 is connected to a humidity sensor whose 4mA value corresponds to 0% relative humidity, and whose 20mA value corresponds to 100% relative humidity, the CLM100 can measure and transmit humidity at a resolution of 0.33% relative humidity. However, NMEA 2000 can represent humidity at a resolution of 0.004%. In this case, the capabilities of the CLM100 is what limits the resolution of the parameter values that will be transmitted over the network to 0.33%.

 

Depending on the type of data being monitored, resolution might further be limited by the resolution of the underlying NMEA 2000 data types used to transmit the parameter value. For example, if you connected a DC voltage sensor with a range of 0-20VDC to the CLM100, the CLM100 could measure the parameter transmitted by the CLM100 to a resolution of 0.067V; however, NMEA 2000 can only represent voltage to a resolution of 0.1V, so in this case, the NMEA 2000 data representation is what limits the resolution of the parameter values that will be transmitted over the NMEA 2000 network to 0.1V.

 

Finally, the resolution to which the CLM100 can measure a parameter may be limited by the current loop transducer. If the current loop transducer’s resolution is lower than that of the NMEA 2000 representation and the CLM100’s current measurement capability, then the resolution of the current loop transducer will limit the resolution of the value that will be transmitted over the NMEA 2000 network.

 

Please refer to the configuration section (Section 4) for information on units and NMEA 2000 range and resolution for the different data types supported by the CLM100.

 

1.8      Accuracy

The CLM100’s accuracy is specified at 1% of the full scale. From the previous example, that means that the humidity value transmitted by the CLM100 will be within 1% of the humidity value transmitted by the humidity sensor over its 4-20mA current loop interface.  When considering the accuracy of the measurement on the NMEA 2000 network, the accuracy specification of the sensor itself needs to be considered along with the CLM100’s accuracy specification.

3      Installation

3.1   Unpacking the Box

When unpacking the box containing the Maretron CLM100, you should find the following items:

 

·         1 – CLM100 Current Loop Monitor

·         1 – Parts Bag containing 4 Stainless Steel Mounting Screws

·         1 – CLM100 User’s Manual

·         1 – Warranty Registration Card

 

If any of these items are missing or damaged, please contact Maretron.

 

3.2   Choosing a Mounting Location

Please consider the following when choosing a mounting location.

 

  1. The CLM100 is waterproof, so it can be mounted in a damp or dry location.
  2. The orientation is not important, so the CLM100 can be mounted on a horizontal deck, vertical bulkhead, or upside down if desired.
  3.  The CLM100 is temperature-rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit. 

 

3.3   Mounting the CLM100

Attach the CLM100 securely to the vessel using the included stainless steel mounting screws or other fasteners as shown in Figure 1Figure 1 below. Do not use threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure.

 

 

Figure 1 – Mounting the CLM100

3.4   Mounting the Transducer

Please refer to the instructions supplied with the transducer for mounting the transducer.

 

3.5   Connecting the CLM100

The CLM100 requires two types of electrical connections: 1) the NMEA 2000® connection (refer to Section 3.5.1), and 2) the 4-20mA current loop transducer connections, which are described in Section 3.5.2.

 

3.5.1     NMEA 2000® Connection

The NMEA 2000® connector can be found on the side of the enclosure. The NMEA 2000® connector is a round five pin male connector (see Figure 2Figure 2). You connect the CLM100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or an NMEA 2000® compatible cable) by connecting the female end of the cable to the CLM100 (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. Connect the other end of the cable (male) to the NMEA 2000® network in the same manner. The CLM100 is designed such that you can plug or unplug it from an NMEA 2000® network while the power to the network is connected or disconnected. Please follow recommended practices for installing NMEA 2000® network products.

Figure 2 – NMEA 2000® Connector Face Views

3.5.2     Transducer Connections

The CLM100 transducer connections are made by connecting to the 12-pin terminal strip on the top of the unit.  First, remove the four screws at the corners of the unit detaching the splash guard from the unit.  On the bottom of the splash guard, you will find a label detailing the wire connection to pin number assignments, which are repeated in the table below.

Warning-Symbol.png

 

WARNING

 

The CLM100 supplies loop power each the 4-20mA current loop transducer. Do not connect the current loop wires from the transducer to anything except for the terminals on the CLM100. Do not connect any external power supply or gauge to the transducer wires that form the current loop.

 

Figure 3 – 4-20mA Transducer Connection Diagram

 

3.5.3     Extension of Transducer Wires

 

Warning-Symbol.png

 

WARNING

 

The transducer cable may be extended. However, you must ensure that when the transducer is connected to the CLM100 with the extended cable, the excitation voltage measured at the transducer meets the minimum excitation voltage specification of the transducer when the transducer is sourcing 20mA.

 

The CLM100 supplies a minimum of 12V to each transducer at the maximum loop current of 20mA. In order to ensure that your transducer will work with extended wires, you should calculate the voltage drop across the extension wires. The amount of voltage drop can be calculated as follows:

 

Look up the resistance per unit length of the wire you are using () from the following table. Be sure to use the value which matches your length measurement units:

Calculate the voltage drop across the cable by multiplying the maximum current (20mA) times the length of the cable. For example, if you are extending the cable by 500 ft. and are using 22AWG wire, then the voltage drop is calculated as follows:

 

First, calculate the resistance of the wire RWIRE. Remember that the wire length LWIRE needs to be multiplied by two, because the current needs to travel from the CLM100 to the transducer and then back again.

 

 

Now, multiply the resistance of the wire by the maximum current (20mA) to calculate the total voltage drop across the extension cable .

 

 

Finally, subtract the voltage drop from the minimum power supply voltage created by the CLM100 to calculate the voltage at the transducer .

 

 

So, for this example, if your transducer can operate with a minimum supply voltage of 11.68V, the wire can be extended to this length.

 

If your calculated  is less than the minimum supply voltage specification of your transducer, then you have two choices:

·         Move the CLM100 closer to the transducer to reduce the wire length, or

·         Use a larger gauge wire to reduce the wire resistance

 

 

4      Configuring the CLM100

The CLM100 has several configurable parameters, which are shown below including the default values. If you are not using the default values, then you will need to refer to the corresponding section for configuring the CLM100 appropriately.

 

The CLM100 can be configured using Maretron’s DSM150 or DSM250 display, or with Maretron’s freely-available N2KAnalyzer software running on a Windows PC interfacing to the NMEA 2000 network through a Maretron USB100 or IPG100 gateway. Please refer to the appropriate configuration tool’s user’s manual for details on how to configure the CLM100 with that product.

 

4.1      Configuring Channel Mode

The CLM100 has 6 individually configurable channels. Each channel can be programmed to operate in one of the following modes:

 

·         DC Voltage

·         DC Current

·         Flow Rate

·         Distance

·         Linear Velocity

·         Linear Acceleration

·         Angle

·         Angular Velocity

·         Angular Acceleration

·         Temperature

·         Humidity

·         Resistance

·         Strain Gauge

·         Force (Load Cell)

·         Pressure

·         Decibels

·         Rotational Rate (Shaft Speed, RPM)

·         Disable – The channel is disabled and transmits no data over the NMEA 2000 network

 

The Disable mode requires no configuration. The following sections describe in detail the configuration of a CLM100 channel for the other operating modes.

 

4.2      Configuring a Channel in DC Voltage Mode

The following sections describe the parameters that are available for configuration for a channel which has been set to DC Voltage mode.

 

4.2.1     Configuring Instance

Program this parameter to match the desired instance of the DC voltage reading for this channel. You can program this parameter to any value between 0 and 252.

 

Warning-Symbol.png

 

NOTE

6      Troubleshooting

If you notice unexpected operation of the Maretron CLM100, follow the troubleshooting procedures in this section to remedy simple problems.

 


Symptom

Troubleshooting Procedure

No transducer data visible on NMEA 2000® network.

1.    Ensure that the CLM100 is properly connected to the NMEA 2000® network.

2.    Ensure that transducers are properly connected to the CLM100.

3.    Ensure that each channel that you wish to monitor is configured as the appropriate mode and that instance numbers are configured correctly.

4.    Ensure that the CLM100 has the appropriate NMEA 2000 PGNs enabled.

Inaccurate transducer value

1.    Ensure that the “Value at 4mA” and “Value at 20mA” configuration items are set to appropriate values for the transducer.

2.    Check that the vent tube from any pressure transducer (only present on some transducers) is not kinked or blocked.

3.    Ensure that nothing is interfering with the ability of the transducer to properly measure its parameter (e.g., clogged ports on pressure transducers).

Zero or “dash” readings on display

1.    Ensure that the “Value at 4mA” and “Value at 20mA” configuration items are set to appropriate values for the transducer.

2.    Check the cable connection to the transducer to see whether a wire has become loose, or the cable has been cut.
