4-1 Control Panel Indicator Lights

PROCESS BLOWER ON

This indicator lights when the process blower is energized.

PROCESS HEATER ON

This indicator lights when the process air heaters are energized.

HIGH PROCESS AIR TEMPERATURE ALARM

;This indicator lights when the temperature at the process air thermocouple is above the set high alarm value.

;When the indicator lights, the alarm relay is energized and all the heaters turn off while the blowers remain on.

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

;When the temperature at the process thermocouple returns to within the acceptable range, the alarm output is de-energized and all the heaters turn on again automatically.

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

REGEN BLOWER ON

This indicator lights when the regeneration blower is energized.

REGEN HEATER ON

This indicator lights when the regeneration heater is on.

LEFT BED REGENERATING & RIGHT BED REGENERATING

The indicator lit shows which bed is currently being regenerated [off-line].

HIGH DEW POINT ALARM

This indicator lights when the process air delivery dew point exceeds the dew point shift point, as set by the adjustment pot on the control enclosure graphic panel. See Section 5-6.

DIRTY FILTER ALARM

;This indicator lights if the pressure differential across either the process air return filter or the regeneration inlet filter exceeds the pressure switch setting.

;This indicates a filter in need of service.

;The light resets automatically when the filter is serviced.

;The pressure switch is adjustable - See Section 6-4.

LOW PROCESS AIR TEMPERATURE ALARM

;This indicator lights when the temperature at the process air thermocouple is below the set low alarm value.
