Sterling 350-2100 CFM installation manual Process Blower Failure Alarm

Page 21

;The alarm mode and value are factory-set to track 25°F below the process setpoint. The alarm value is a deviation above the process setpoint.

;This alarm is informational. If the alarm light stays lit for an extended period of time, check for blown fuses or possible burnt-out heaters.

;When the temperature at the thermocouple returns within limits, the alarm clears automatically.

;This alarm is delayed on initial start-up to avoid nuisance alarms.

;The alarm range may be altered. See Section 5-5.

PROCESS BLOWER FAILURE ALARM

;This indicator lights if pressure switch 2PS detects a loss of process blower air pressure.

;All heaters are shut-off until the alarm is cleared.

REGEN BLOWER FAILURE ALARM

;This indicator lights if pressure switch 1PS detects a loss of regeneration blower air pressure.

;All heaters are shut-off until the alarm is cleared.

HIGH REGEN AIR TEMPERATURE ALARM

This indicator lights when the thermocouple below the regeneration heater assembly senses an abnormally high temperature.

Note: Do not adjust the factory setpoint of 3CNTL, the 116 DIN panel-mounted temperature controller inside the enclosure.

The regeneration heaters are shut-off until the temperature falls below the alarm point. The regeneration blower will continue to run and cool the heaters and desiccant bed.

The alarm light will clear automatically when the temperature drops below the alarm point, and the heaters will re-energize automatically.

LOW REGEN AIR TEMPERATURE

This indicator lights if the regeneration bleed temperature has not reached the factory setpoint of 150°F within 30 minutes of the start of bed regeneration.

The panel meter (2CNTL) and the PLC monitor the regeneration bleed temperature. This alarm is informational, and does not affect the regeneration process.

This alarm may indicate a very wet desiccant bed or, if the light does not go off within an hour, malfunctioning or burnt out regeneration heaters. For more details on the regeneration monitoring system, see Section 5-7.

CRITICAL ALARM SILENCE

Press this button to turn off the audible alarm and flashing beacon when a critical, operation stopping alarm occurs.

The alarm will repeat every five minutes unless the problem causing the alarm has been resolved.
