RESET
The RESET position is used to reset the panel after a THERMAL OVERLOAD, HIGH SUMP/DRUM LEVEL or SYSTEM
PRESSURE condition has occurred. To clear alarm interlocks received by the panel, the BLOWER CONTROL switch
must be held in the RESET position while the PUMP CONTROL switch is toggled from AUTO to RUN, this issues a “clear
interlocks” command and the ALARM ENGAGED indicator will blink quickly. Once this indicator stops blinking, the
BLOWER CONTROL switch can be set back to the RUN position.
BLOWER CONTROL Indicators
These indicators monitor the setting of the BLOWER CONTROL switch and provide information on the status of the
blower.
RUN
The green RUN indicator is illuminated whenever the BLOWER CONTROL switch is in the RUN position. If the BLOWER
CONTROL switch fails, the RUN indicator will blink.
BLOWER RUNNING
When the blower is running the indicator will be steadily illuminated.
BLOWER STATUS Indicators
THERMAL OVERLOAD
If the blower motor thermals have been wired directly to the panel as explained in Chapter 2, the THERMAL OVERLOAD
indicator will be illuminated in the event the blower shuts down because of a thermal overload. This condition is cleared by
turning the BLOWER CONTROL switch to RESET and then back to RUN.
SYSTEM PRESSURE
If either a High or Low Pressure signal is received by the panel, the SYSTEM PRESSURE indicator will be illuminated, the
blower will shut down and the feed pump will shut down (if tied to an interlock). If the shutdown was caused by a Low
Pressure condition, the indicator will blink and the blower will stop immediately. If the shutdown was caused by a High
Pressure condition, the indicator will be steadily illuminated and the blower will stop after a time delay of 3 minutes.
A second time delay prevents the SYSTEM PRESSURE feature from shutting down the blower during the first 5 seconds
of operation. This permits the blower to build normal pressure during startup. The SYSTEM PRESSURE condition is
cleared by turning the BLOWER CONTROL switch to RESET and then back to RUN.
HIGH SUMP/DRUM LEVEL
In air stripper/transfer pump applications, this indicator is illuminated if the air stripper sump fills and lifts the OVERRIDE
float on the sump level probe. In SVE/knockout drum pump applications, the indicator is illuminated if the knockout drum
becomes full and activates the high level switch.
In air stripper/transfer pump applications, neither blower nor transfer pump is shut down by a HIGH SUMP signal.
However, both can be shut down if the signal is tied to an interlock.
Before restarting the blower, determine and rectify the cause of the
thermal overload.
If a jumper is installed between terminals TB4-5 and TB4-7, the blower will stop
after 7 seconds.
