Indicator

Name

Description

 

 

compressed air, the pressure switch opens and sends

 

 

a signal to the PLC controller to shut down dryer

 

 

operation. Dryer operation automatically resumes

 

 

when 80 psi (551 kPa/ 5.51 bars) air is restored.

 

High Temp

The High Temp Process Air alarm indicator lights

 

Process Air Light

when the temperature at the process air

 

 

thermocouple is above the high alarm set value.

 

 

Upon high temperature alarm condition the process

 

 

heaters turn off, the process blower remain on.

R

 

The alarm mode and value are factory-set to track

 

 

25º above the process set point. The alarm value is

 

 

an upper-limit deviation above the process set point.

 

 

When the temperature at the process thermocouple

 

 

returns to within the acceptable range, the alarm

 

 

output de-energizes and all heaters turn on again

 

 

automatically.

 

High Temp

The High Temperature Regen Air alarm indicator

 

Regen Air Light

lights when the thermostat above the regeneration

 

 

heater assembly senses an abnormally high

 

 

temperature.

R

 

The regeneration heaters shut down until the

 

temperature falls below the alarm point. The

 

 

 

 

regeneration blower continues to run for cooling the

 

 

heaters and desiccant bed. The alarm condition

 

 

clears when the temperature drops below the

 

 

thermostat setpoint. The heaters re-energize

 

 

automatically.

A

High Dew Point

The High Dew Point alarm indicator lights when the

Light

process air delivery dew point exceeds a dew point

 

 

of -10°F (-23°C).

G

Material Loading

The Material Loading indicator lights when material

Light

is being conveyed.

 

Optional Dirty

If installed, the Dirty Filter alarm indicator lights

 

Filter Light

when the pressure differential across the process,

 

 

regeneration and conveying air return filter exceeds

A

 

the pressure switch setting. Service the filter when

 

 

this indicator lights. The indicator and the alarm

 

 

condition clears after you service and reinstall the

 

 

filter.
