Obviously, pressure measurement errors will be encountered if 'zeroing' is done with pressure at the
transducer. If large errors are detected, the controller will demand that the transducer be checked.
3. In the top line, "REMOVE RES PRESS" is displayed. The bottom line displays the current pressure
being sensed in the reservoir. The reservoir pressure transducer may now be 'zeroed' by following
the steps outlined in step 2 above.
4. This completes the configuration adjustments. The controller will return to the main adjustments
menu.
Unit Setup Adjustments
1. In the top line, "OIL CHANGE INTERVAL" is displayed. The bottom line will indicate a time interval of
1000 to 12000 hours. After the machine has run for the programmed setting, an advisory will be
displayed, requesting an oil change. Adjust as desired and press [ENTER] to proceed.
2. In the top line, "FILTER CHNG INTERVAL" is displayed. The bottom line will indicate a time interval
of 500 to 1200 hours. After the machine has run for the programmed setting, an advisory will be
displayed, requesting an oil filter change. Adjust as desired and press [ENTER] to proceed.
3. In the top line, "OVER TEMP LIMIT" is displayed. The bottom line will indicate 225 degrees F. This
is the proper setting for compressor operation with conventional coolant. It may be set higher for high
temperature oils, per the manufacturer's instructions. It may be temporarily lowered to verify the
function of the temperature shutdown system.
4. In the top line, "AUTO RESTART" is displayed. The bottom line will indicate either "OFF" or "ON".
The factory setting is "OFF", and the controller will display a power failure shutdown after power has
been restored.
Set this feature to ON when it is necessary to have the compressor automatically restart after a
power interruption. There will be a brief delay, then the control resumes the mode it was in prior to
the interruption. This feature shall only be enabled when the owner determines that it is safe to do
so. It is recommended that compressor access be limited to only trained service personnel when this
feature is used.
5. This step is only encountered if the AUTO RESTART function was set to ON in the previous step. In
the top line, "RESTART DELAY" is displayed. The bottom line will indicate a time between 5 and 30
seconds. It is factory set at 10 seconds. This is the amount of delay introduced before restarting
after power has been restored. Set it as desired to allow time for power to stabilize before starting
compressors.
6. The display now reads "JOG MOTOR?" and indicates the amount of time to energize the starter.
Adjust with the [+] or [-] key to the smallest value needed to bump the motor and check rotation. 0.1
to 0.2 seconds is normally adequate for factory-furnished full-voltage starters; wye-delta or remote
starters may require a little more time. Set back to zero to proceed to the next step.
7.
This completes the unit setup adjustments. The controller will return to the main adjustments menu.
CONNECTION TO EXTERNAL CONTROLS
The controller offers interconnection points for external controls and indicators. This allows simple
connection to remote controls and indicators, or integration into any plantwide controls system.
