8.4 ELECTRICaL CONNECTION
Equipment is available in various electrical configurations. All
customer connections can be made at the contactor located
in the control panel. (Refer to General Arrangement and
appropriate Wiring Diagrams.)
A suitable fused disconnect switch or circuit breaker, in
accordance with national and local code requirements, is
recommended for all Ingersoll Rand equipment. Refer to
Section 15 for voltage requirements and load.
CAUTION
Never wire directly or connect any additional wires to
the compressor junction box. This will cause severe
system malfunction.
8.4.1 Ingersoll Rand dryers can be configured for three
variations of start modes: Manual Mode, Automatic Mode
and Remote Mode. Refer to Section 10 for instructions on
how to change the dryer’s start settings. The instructions
below describe the methods to configure the dryer for a
particular Start Mode.
A) Manual Mode (Factory Default) - No modification
required to operate dryer in Manual Mode. Once
power is applied, dryer can be started or stopped by
depressing the local ON / OFF pushbuttons located
on the front panel.
B) Auto Restart Mode - Auto Restart Mode permits the
dryer to start after a brief delay once power is applied
to the dryer. Note that the dryer’s touch pad will still
affect dryer operation. Depressing the OFF button
will de-energize the refrigeration compressor and all
other electrical components. After the OFF button has
been depressed, the user must depress the ON button
to permit the dryer to operate.
C) Remote Mode - Remote Mode allows the dryer to be
turned ON or OFF via a remote switch supplied by
the customer. This mode will work regardless of the
setting for Auto Restart. The dryer must be powered
on for this feature to take effect. To enable this
feature:
Install N.O. remote switch as indicated on the
appropriate wiring diagram.
Customer-supplied contact should be rated at 1A
at 24V. To operate dryer, close switch or contact and
allow dryer to start after an initial delay. The local On
/ OFF pushbuttons may also be used at any time after
contact closure.

8.5 INITIaL STaRT-UP
NOTICE
For water cooled models, the water valve must be
manually opened to ensure that the condenser is full
of water prior to start-up.
CAUTION
allow 8 hours of warm-up time for the crankcase heater
prior to start up. Crankcase heater is connected directly
to the incoming power and is energized at all times.
8.5.1 START- UP SEQUENCE
Apply power to dryer. LCD Panel will illuminate. The
Anti-Short Cycle delay will commence counting
down. Remaining time on the Crankcase heater will
also countdown.
NOTICE
after installation or a prolonged shutdown, start the
dryer with no air load (no air flow). This enables the
dryer to reach its proper operating temperature in the
shortest time possible.
Start Dryer, using one of the following methods,
depending on Start Mode setting:
Manual Mode - Press the ON pushbutton.
Auto Restart Mode - No additional action required
Remote Automatic Mode - Close the remote contact.
Anti-short cycle delay and crankcase heater delay
have timed out, the refrigeration system will energize.
After the alarm delay, provided the Chiller Temperature is
greater than the HIGH TEMPERATURE ALARM set point, the
dryer will go into HIGH TEMPERATURE ALARM. The LCD panel
will indicate the alarm and the refrigeration system will
continue to operate. Pressing the SELECT DISPLAY button
will permit viewing of the available dryer parameters during
this alarm condition. Note that the alarm condition screen
will reappear after approximately 30 seconds until the alarm
condition is cleared.
The CHILLER TEMPERATURE will gradually drop as indicated
on the display. Once the temperature falls below the HIGH
TEMPERATURE ALARM set point, the alarm will reset and the
LCD panel will return to its default display. Air flow may be
slowly introduced to the dryer.
NOTICE
If power is removed from the dryer for less than two
hours, the crankcase heater delay will be automatically
bypassed. If, however, the power is removed from
the dryer for more than two hours, the full crankcase
heater delay must be observed.
