ALARMS / SHUTDOWNS
OVERVIEW
In addition to the Alarms and Shutdowns that the Quantum
™
LX
software generates for the basic compressor package,
there are warnings and shutdowns that are associated with
the Vyper
™
drive operation. These can be initiated by the
Quantum
™
LX panel or the Vyper
™
drive. The following pages
describe these warnings and shutdowns by title and descrip-
tion as well as the cause and items to check.
When a Shutdown occurs, the display backlight will flash on
and off to alert an operator of the shutdown. This visual alarm
will help get the attention of the operator in a noisy engine room
environment where audible alarms may not be heard. Pressing
any key on the keypad will clear the flashing backlight alarm.
The FRICK VYPER
™
FAULT CODES table shows the full list-
ing of fault codes. A detailed description and troubleshooting
recommendations follow.
The following warnings and or shutdowns are initiated by
the Quantum
™
LX panel. These safeties are set for When
Running:
High Motor Stator Temp. – If the motor stator temperature
rises above a critical point, one or more embedded thermistors
will open, removing the digital input to the Dig. Aux. #1 module,
wire #28 (typical). There is one thermistor per winding.
If the motor is equipped with stator RTDs (one per winding)
the same result will occur only that the signal is now an analog
signal and is set up as one of the PHD monitoring channels.
The warning and shutdown values can be seen on the PHD
setpoints screen of the
Quantum
™
LX panel and should be
set based on the limits of the motor’s insulation class.
Blower Motor Aux. – If the motor is equipped with auxiliary
blowers mounted to the top of the main drive motor, then a
confirmed run signal is required. This signal is in the form of
a digital signal from the Aux. Contacts of the blower motor
starter/s and is received by Dig. Aux. #2, wire #29 (typical).
High Vyper Coolant Temp. – The Vyper Coolant Temp. is
monitored by the
Quantum
™
LX Panel from a temperature
probe mounted at the coolant reservoir on analog auxiliary
#9 (Ch. 13 analog brd #2). If the Vyper
™
Coolant exceeds
the High Temp Warning or Shutdown values for the delays,
this warning or shutdown will occur. These values can be
seen on page 2 of the Analog Auxiliaries setpoints screens.
Default settings are 130°F for the warning, 135°F for the
shutdown.
Low Vyper Coolant Temp. – The Vyper Coolant Temp. is
monitored by the
Quantum
™
LX Panel from a temperature
probe mounted at the coolant reservoir on analog auxiliary
#9 (Ch. 13 analog brd #2). If the Vyper Coolant exceeds the
Low Temp Warning or Shutdown values for the delays, this
warning or shutdown will occur. These values can be seen on
page 2 of the Analog Auxiliaries setpoints screens. Default
settings are 85°F for the warning, 80°F for the shutdown.
NOTE: If the compressor has been down for an extended
period and the ambient temperature is less than the Low
Vyper Coolant Temp. warning or shutdown values, it may
be necessary to lower these settings temporarily in order
to get the drive running.
This setpoint can never be set
lower than 5° F above ambient dry
bulb temperature. If not sure of dry
bulb temperature, DO NOT GUESS.
Once the drive is running with the coolant temperature back
above the default setting for this safety, go back and change
them to 85°F for the warning and 80°F for the shutdown.
The warnings and shutdowns on the following pages are
initiated by the Vyper
™
drive and communicated to the
Quantum
™
LX panel for display and clearing purposes.
