Steps
Alarm/Cause
Corrective Action
61
DOOR OPEN (DS1)
•
TRIGGER–ON: DS1 is set to activate an alarm if the switch is activated (opened or closed, depend-
ing on switch type) for more than five seconds.
•
UNIT CONTROL: May be configured as alarm only, alarm and force low engine speed 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.
IF A SWITCH IS INSTALLED
1
Determine what DS1 is controlled by.
DS1 may be connected to a com-
partment door or some other device
and used to remotely control the unit.
Locate the device used as DS1.
2
Check To See If DS1 Has Activated
Inspect device used to activate DS1. For example, compartment door must be closed, and
switch must be de-activated.
3
Check “DOOR SWITCH” 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
“door switch) Configuration, Table 5

4
Check Wiring
a. Visually inspect wiring to DS1
Wiring must be connected.
b. Visually inspect condition of switch Must not be damaged, wet, corroded, etc.
c. Check circuit. (See wiring schemat-
ic Section 10.)
With the switch contacts closed, check for 12 VDC
through the wiring and switch to the correct micropro-
cessor terminal (refer to applicable wiring schematic -
Section 10).

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 tem-
porarily overridden by setting the
correct Functional Parameter.
In the Functional Parameter list set OVERRIDE
REMS1 SHUTDOWN to YES.
IF A SWITCH IS NOT INSTALLED
Locate and inspect 10 position con-
nector for optional sensors and
switches (REMSN, see wiring sche-
matic Section 10).
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 con-
nector may be removed and each individual wire sep-
arated from the others, terminated and insulated with
heat shrink.
