the TECHNICIAN MODE.
SELECT
DISPLAY
Depressing SELECT DISPLAY scrolls through the
available parameters. The first three parameters viewed are
adjustable in TECHNICIAN MODE.
The DRAIN ENABLE parameter determines whether the
Microprocessor Control shall control the drain valve. A value
of "ON" will permit the Microprocessor Control to control the
drain valve. A value of "OFF" will disable this feature. Ingersoll
Rand dryers are equipped with a solenoid drain as standard
equipment. As such, DRAIN ENABLE must remain "ON"
For Ingersoll Rand dryers equipped with a NO AIR LOSS DRAIN
as equipment, DRAIN ENABLE must remain "OFF"
SELECT
DISPLAY
Depressing the SELECT DISPLAY button advances
to the next adjustable parameter for the Crankcase Heater
Delay. This parameter must not be altered unless instructed by
Ingersoll Rand Service personnel.
NOTICE
The Crankcase Heater Delay set point must not be
altered unless directed by Ingersoll Rand Service
Personnel. Improperly altering the set point may
result in damage to the dryer. Contact Ingersoll Rand
Compressed Air Solutions before altering the default
set point.
The AUTO RESTART feature permits the dryer to operate once
power is applied to the dryer without requiring operator
intervention. This would be desirable should the user wish to
have the dryer restart automatically after a power outage. To
change the AUTO RESTART set point from "N" (NO) to "Y" (YES),
perform the following. Otherwise, depress the SELECT DISPLAY
button to advance to the next display:
