Operating Instructions 6-23
After the unit starts on CYCLE-SENTRY operation, the control system monitors the voltage across the field of the alternator and
will keep the unit operating until the battery is recharged sufficiently. The unit operates in whichever mode the controller requires
to properly maintain the load temperature. When the battery is sufficiently recharged, the unit will shut down on controller
demand.
WARNING: With the selector switch in CYCLE-SENTRY (Auto Start Stop) operation (or CYCLE-SENTRY icon ON in
TG-VI, Multi-Temp MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 display) and the unit On/Off switch in the ON position, the unit
may start at any time without prior warning.
NOTE: Fully charged batteries in good condition are essential for reliable unit operation. This is especially true on
CYCLE-SENTRY equipped units in cold weather.
Starting Units on Continuous Run, Diesel Operation
TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 NOTE: A unit that has been OFF for a long time should be put through a
Full Pre-trip Test before releasing the unit for service.
1. Place Diesel/Electric switch to DIESEL position (Model 50 units).
WARNING: After 10 seconds, the units start automatically when On/Off switch is turned to ON:
CAUTION: Never use starting fluid.
TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 NOTE: If the controller displays the cool or heat icon but the engine does
not start within 15 seconds, turn the unit On/Off switch to OFF. Check and correct any alarm code conditions. Also check
and correct the engine control circuit and engine for the cause of the failure. Then repeat start procedure.
NOTE: Place each rear compartment (Zone 2, Zone 3) On/Off switch in the ON position to start the remote evaporators
Starting Units on CYCLE-SENTRY, Diesel Operation
1. On Model 50 units, place the Diesel/Electric switch in the DIESEL position.
2. Select CYCLE-SENTRY operation:
• TG-VI, Multi-Temp MT µP-IV, µP-V, µP-VI, SR-2 or SR-3 controllers: set the CYCLS display in the controller menu to
CYCLS ON (CYCLE-SENTRY icon in controller display ON).
3. Place the unit (or Zone 1) On/Off switch in ON position. The CYCLE-SENTRY symbol should appear (TG-VI, MT µP-IV,
µP-V, µP-VI , SR-2 and SR-3 controllers).
4. Set the compartment (Zone 1) setpoint at the desired temperature. DO NOT adjust the setpoint lower than required (lowering
the setpoint does not make the unit cool faster).
5. If the controller calls for cool or heat, the cool or heat symbol (TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 controllers)
will be ON and the glow plugs (or air heater) will automatically preheat (if necessary). Preheat time ranges from 5 to 120
seconds, depending on the engine temperature.
6. At the end of the preheat period, the engine then begins cranking. The glow plugs (or air heater) and the preheat buzzer are
energised during the cranking period. If the engine rpm does not exceed 50 rpm during the first 4 seconds of cranking, or if
the engine does not start after 30 seconds of cranking, the cranking cycle terminates.
NOTE: Units with a µP-V, µP-VI(Except Multi-Temp MT µP-IV), SR-2 or SR-3 controller include a CYCLE-SENTRY Fresh
(CSFR) feature. If CSFR is active and the setpoint is within the programmed lockout range, the CYCLE-SENTRY symbol will
flash while the unit is automatically starting. After the unit starts, the CYCLE-SENTRY symbol will disappear and the unit
will operate in Continuous Run as long as the setpoint is within the programmed lockout range. The CYCLE-SENTRY light
on the optional remote indicator light assembly will remain on, indicating that the CYCLE-SENTRY switch is in the
CYCLE-SENTRY position.
7. If the engine fails to start, place the unit switch in the OFF position. Determine and correct the cause of the starting failure.
TG-VI, MT µP-IV, µP-V, µP-VI , SR-2 and SR-3 NOTE: If the controller displays the cool or heat icon but the engine does
not start within 15 seconds, turn the unit On/Off switch to OFF. Check and correct any alarm code conditions. Also check
and correct the engine control circuit and engine for the cause of the failure. Then repeat start procedure.
NOTE: Place each remote compartment (Zone 2, Zone 3) On/Off switch in the ON position to start the remote evaporators.
Then set remote compartment setpoint at desired temperature.
