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)

Revision 1.0 Page 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.
