ALARM MESSAGE
| POSSIBLE CAUSE | POSSIBLE SOLUTION |
High Temp Probe 1 High Temp Probe 2 High Temp Probe 3
High
Temp Probe 4 | The temperature associated
with a probe has gone above the high temperature alarm point and past any alarm
biasing. | - Try lowering the temperature by turning heaters down or off, or by
increasing or turning on cooling elements (such as fans or misters), or by a
combination of both.
- Check the temperature probes.
- Check to see if a fan has failed.
- Check settings.
- Check if probe averaging is
enabled and configured correctly.
|
Low Temp Probe 1 Low Temp Probe 2 Low Temp Probe 3
Low Temp Probe 4 | The temperature associated
with a probe has gone below the low temperature alarm point. | - Try to raise the temperature by turning heaters up or on, or by
decreasing or turning off cooling elements (such as fans or misters), or by a
combination of both.
- Check the temperature probes.
- Check to see if a heater has failed.
- Check settings,
- Check if probe averaging is
enabled and configured correctly.
|
Probe 1 Shorted Probe 2 Shorted Probe 3 Shorted
Probe 4 Shorted | An active temperature probe
has shorted. | - The next active Probe will be used. If Averaging is ON, the
defective probe will be excluded from the average.
- Replace the temperature
probe. The control should recover automatically.
|
Probe 1 Absent Probe 2 Absent Probe 3 Absent
Probe 4 Absent
| An active temperature probe
has disconnected. | - The next active Probe will be used. If Averaging is ON, the
defective probe will be excluded from the average.
- Reconnect the temperature
probe. The control should recover automatically.
|
Actuator 1 Jam
Actuator 2 Jam | The Supra is attempting to
open or close an inlet or other element operated by an actuator, and has not
received the correct response from the positioning motor. | - Check the element controlled by the
actuator to see if it is mechanically stuck.
- Check the feedback wires
for damage.
|
Error (for a relay during the status display) | You have configured an
“open relay” for an actuator or curtain, but not a “close relay”. | - Check the relay
configuration and configure the close relay.
|
Low AC Line Frequency
High AC Line Frequency | The AC line frequency is
outside acceptable limits (±3 Hz at rated line frequency). There is a danger of
damaging the control if this condition persists. | - Consult your local power company.
- If using generator power,
adjust the generator frequency to 60Hz (or 50Hz).
|
Low Power Volt
High Power Volt | AC power supply is outside
acceptable limits (+10%/-20% at rated line voltage). | - Consult an electrician or
your local power company.
|
PC Comm. Alarm | The communication cable
between the Supra and the computer is damaged or disconnected. | - Check the cable.
- Verify that cable leads are
properly seated in terminal block.
