1F5 Compressor Did Not
Accelerate Fully
Immediate Latch The starter module did not receive an “Up to Speed” or “End of
Ramp” signal from the SSS within 2.5 seconds after commanding
a bypass, or after the maximum acceleration time had expired,
whichever is longer. This diagnostic only applies to SSS.
Local
EE Compressor Did Not
Accelerate: Shut-
down
Immediate Latch The compressor did not come up to speed (get to <85%RLA) in
the allotted time dened by the Maximum Acceleration Timer and
and the start was aborted per the starter conguration selected.
Remote
1FA Compressor Did Not
Accelerate: Transi-
tion
Info Latch The compressor did not come up to speed (get to <85%RLA) in
the allotted time dened by the Maximum Acceleration Timer and
a transition was forced (motor put across the line) at that time.
This applies to all starter types. Note: Since RTHD SSS has no
forced transition capability, this info warning can be followed with
a “Compressor did not accelerate fully “ diagnostic above and an
aborted start.

F7 Condenser Water
Flow Lost
Immediate NonLatch The condenser water ow proof input was open for more than 6
contiguous seconds after ow had been proven. This diagnostic is
automatically cleared once the compressor is stopped by a xed
time out of 7 sec. The Cond Pump shall be commanded off but
the Evap pump command will not be effected.

DC Condenser Water
Flow Overdue
Normal NonLatch Condenser water ow was not proven within 20 minutes of the
condenser pump relay being energized. The Cond Pump shall be
commanded off. Diagnostic is reset with return of ow (although
only possible with external control of pump)

Overload
Immediate Latch Compressor current exceeded overload time vs. trip characteris-
tic. For A/C products Must trip = 140% RLA, Must hold=125%,
nominal trip 132.5% in 30 seconds

FD Emergency Stop Immediate Latch a. EMERGENCY STOP input is open. An external interlock has
tripped. Time to trip from input opening to unit stop shall be 0.1
to 1.0 seconds.

Sensor
Info Latch Bad Sensor or LLID Normal operation unless CHW Reset is en-
abled. If CHW Reset is enabled and either Return or Constant
Return Chilled Water Reset is selected, its effect will be removed
but slew rates on the change will be limited per the Chilled Water
Reset spec.
