Screen 1
The set-up code for Screen 1 represents a
combination of the following seven settings:
1. Save Elapsed Time
Elapsed time is the duration between the end
of one Defrost cycle and the beginning of the
next.
The TG-V Microprocessor Controller has a
built in defrost interval timer which can
automatically initiate a Defrost cycle after a
preset period of time has elapsed.
When the Thermo King unit is switched Off,
the defrost interval timer can be set to do one
of two things:
•
It can save the time which has elapsed
since the last defrost and continue on when
the unit is restarted.
•
Or, it can reset and start timing again from
the beginning.
Example: Defrost interval time is set to 2
hours. The unit is switched Off after 1 hour
(that is, a defrost interval of 1 hour has
elapsed):
•
If the elapsed time has been saved; when
the unit is turned back On, the timer could
initiate defrost 1 hour later. The total
interval is 1 hour of elapsed time plus 1
hour of time since the unit was turned On.
•
If the elapsed time has not been saved;
when the unit is turned back On, the timer
will reset and start timing again from the
beginning. The timer could initiate defrost
2 hours from the time the unit was turned
back On.
The Microprocessor Controller should be set
to save elapsed time:
•
In delivery applications where the unit will
be turned On and Off before a normal
defrost time has elapsed.
•
In units without an air switch.
Elapsed time should not be saved in normal,
over-the-road applications where the unit is
run continuously and is not frequently turned
Off and On.
Settings:
YES = Save elapsed time.
NO = Do not save elapsed time.
2. Defrost Terminate Time
If a Defrost cycle is not terminated
automatically, the TG-V Microprocessor
Controller terminates the Defrost cycle after
the programmed period of time.
Settings:
30 minutes or 45 minutes.
3. High Speed Delay
To save fuel when the cargo compartment
temperature is in range, the TG-V
Microprocessor Controller can delay high
speed heat or high speed cool for 8 minutes.
Settings:
YES = Delay high speed operation for 8
minutes.
NO = Do not delay high speed operation
for 8 minutes.
NOTE: In order for the High Speed Delay to
operate, the 7K terminal must be used.
NOTE: Low Speed heat is only available in
Continuous Run operation. In
CYCLE-SENTRY, the unit restarts and runs
in High Speed Heat.
