Level
3D7 Transition Complete
Input Opened
Immediate Latch The Transition Complete input is open with the compressor motor
running after a successful completion of transition. This is active
only for all electromechanical starters
Local
3D5 Transition Complete
Input Shorted
Immediate Latch The Transition Complete input is shorted before the compressor
was started. This is active for all electromechanical starters.

D8 Under Voltage Normal Non Latch a. Average of all monitored Line voltages below - 10% of nomi-
nal or the Under/Overvoltage transformer( s) are not connected.
[Must hold = - 10 % of nominal. Must trip = - 15 % of nominal.
Reset differential = min. of 2% and max. of 4%. Time to trip =
min. of 1 min. and max. of 5 min.) Design: Nom. trip: 60 sec-
onds at less than 87.5%, + or - 2.8% at 200V or + or - 1.8% at
575V, Auto Reset at 90% or greater.

6B6 Heat recovery ow
delay
Alarm Non Latch The water in the heat recovery pipeline cannot be proved to
be owing in 20 minutes after the heat recovery pump relay is
added. The heat recovery pump will be ordered to stop when
the heat recovery line detects the ow of water and the alarm is
cleared.
Remote
6B6 The heat recovery
ow is short
Immediate Non Latch The input disconnection of the ow of the heat recovery pipeline
is more than 6 seconds after conrming the ow. The compressor
is automatically cleared after 7 seconds.
Remote
6B6 Undesired ow -
main condenser
Warning Non Latch When the main condenser is ordered to shut down, it will con-
tinue to monitor the presence of water. Once the water ow is
detected, the alarm will be automatically cleared.
Remote
6B6 Undesired ow - heat
recovery condenser
Warning Non Latch When the heat recovery condenser is ordered to be shut down
for 180 days, it will continue to monitor the presence of water.
Once the water ow is detected, the alarm will be automatically
cleared.
