What to do if my Sullair DEX shows a loss of power alarm?
If you're getting a 'Loss of power alarm' on your Sullair Dryer, start by checking the control circuit fuse and replace it if needed. Also, check the PLC to see if any outputs are 'on' or if the PLC alarm LED is lit; replace the PLC if necessary. Finally, verify that the system's incoming power supply is active and restore it if it has been lost.
How to fix high humidity alarm on Sullair DEX Dryer?
If your Sullair Dryer displays a high humidity alarm, which may come with an optional dew point monitor, you should first reset the alarm using the “Alarm Reset” push button. Then, check the heating and cooling operations by watching the regenerations, ensuring the regeneration temperatures match those in Section 3.7. Also, make sure that the dewpoint probe service valves are open.
What causes regeneration heater sheath over temperature failure in Sullair DEX Dryer?
If the Sullair Dryer shows a 'Regeneration heater sheath over temperature failure', replace the thermocouple. Also, check the regeneration blower, motor, motor overloads, and inlet filter, replacing parts as needed. If those aren't the problem, replace the temperature switch.
What to do if Sullair DEX Dryer displays blower overload alarm?
If your Sullair Dryer is showing a Blower overload alarm, check the motor overload to see if it is defective. Also, check the operating conditions to see if the motor is operating overloaded due to a problem with the blower or motor bearing.
How to troubleshoot vessel #1 de-pressurization failure on Sullair DEX?
If Vessel #1 fails to depressurize on your Sullair Dryer, start by checking the solenoid valves and valve actuator for correct operation. If that's not the issue, check if the depressurization muffler is plugged. If the vessel depressurized but the alarm is still on, check the pressure switch for correct operation.
What to do if vessel #2 de-pressurization fails on Sullair DEX?
If Vessel #2 fails to depressurize on your Sullair Dryer, check the solenoid valve and the valve actuator for correct operation. Also, verify that the depressurization muffler isn't plugged. If the vessel did depressurize but the alarm is still active, check the pressure switch for proper operation.
Why is vessel #1 re-pressurization failing on my Sullair DEX Dryer?
If Vessel #1 fails to re-pressurize on your Sullair Dryer, check the air actuated ball valve for correct operation. Also, check the valve actuator and the pilot solenoid valve. If the vessel re-pressurized but the alarm remains on, check pressure switch PSH-1 for correct operation.
How to fix vessel #2 re-pressurization problem in Sullair DEX?
If Vessel #2 is experiencing re-pressurization issues on your Sullair Dryer, check the pilot solenoid valve for correct operation. Also, check the valve actuator. If the vessel re-pressurized, but the alarm is still on, check pressure switch PSH-2 for correct operation.
Why is there low operating pressure during regeneration in my Sullair DEX?
If you're experiencing low operating pressure during regeneration with your Sullair Dryer, first check the compressor to ensure it is running. Also, check all manual valves upstream of the dryer and open them as needed.
