Check Remote Switch 3 (REMS3)
system
Description
REMS3 stayed activated for more than five seconds, and the unit may alarm only, force low engine speed, or shut down.
Activation Conditions
REMS3 is set to trigger an alarm if the switch is activated (opened or closed, depending on switch type) for more than five seconds.
Unit Behavior
Engine and Electric Operation: May be configured as alarm only, alarm and force low engine speed or alarm and shutdown.
Reset Conditions
Alarm Only: Auto reset after the switch has de-activated for more than five seconds. Shutdown: Auto reset after three minutes (minimum off time for switch activated condition) and the switch has de-activated for more than five seconds.
Corrective Actions
If a switch is installed: 1. Determine What REMS3 Is Activated By - REMS3 may be connected to a compartment door or some other device. Locate the device used as REMS3. 2. Check To See If REMS3 Has Activated - Inspect device used to activate REMS3. For example, Compartment door must be closed, and switch must be de-activated. 3. Check Configuration for REMS3 - Verify that Configuration is set for the type of switch being used (i.e. when switch is activated, switch contacts are closed; etc). Configuration must agree with switch type. Refer to Section 5.2.3. 4. Check Wiring a. Visually inspect wiring to REMS3. Wiring must be connected. b. Visually inspect condition of switch. Must not be damaged, wet, corroded, etc. c. Check circuit. (See wiring schematic Section 8.) 5. Temporary Solution Tip - In the event of a defective switch that can not be repaired or replaced, and the switch is forcing the unit into a shutdown or low speed, this action may be temporarily overridden by setting the correct Functional Parameter. Set the OVERRIDE REMS3 SHUTDOWN Functional Parameter to YES. If a switch is not installed: 6. Check Configurations - Any switch/sensor not present in the unit should not be Configured “ON”. Correct Configurations. 7. Check REM Connector - Locate and inspect 10-pin connector for optional sensors and switches (see wiring schematic Section 8). Connector must have cap on, no corrosion or moisture inside connector. If there is a problem with the connector and there are no remote sensors or switches in the unit, the connector may be removed and each individual wire separated from the others, terminated and insulated with heat shrink.
