00058 CHECK REMOTE SWITCH 2 (REMS2)
• ACTIVATION: Remote Switch 2 is set to activate an alarm if the switch is activated (opened or closed,
depending on switch type) for more than five seconds.
• UNIT CONTROL: May be configured as alarm only or alarm and shutdown.
• RESET CONDITION:
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 door open condition) and the switch
has de-activated for more than five seconds.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active
alarm should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
IF A SWITCH IS INSTALLED
1. Determine what REMS2 is Controlled By - REMS2 may be connected to a compartment door or some
other device and used to remotely control the compartment. Locate the device used as REMS2.
2. Check To See If REMS2 Has Activated - Inspect device used to activate REMS2. For example, com-
partment door must be closed, and switch must be de-activated.
3. Check REMS2 (Remote Switch 2) Configuration - 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 Remote Switch #2. Wiring must be connected.
b. Visually inspect condition of switch. Must not be damaged, wet, corroded, etc.
c. Check circuit. (See wiring schematic Section 10.3.) With the switch contacts closed, check for
minimum 11 VDC from 2SVM-15 through the wiring and switch back to 2SVM-26.
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, this alarm may be temporarily overridden by setting the correct
Functional Parameter. In the Functional Parameter list set OVERRIDE REMS2 SHUTDOWN to YES.
IF A SWITCH IS NOT INSTALLED
Locate and inspect 10 position connector for optional sensors and switches (REMSN, see wiring sche-
matic Section 10.3). 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.
