Select Desired Operating Mode
The purge unit has three (3) operational modes. Select desired mode by pressing one of the following
keypad switches (MANUAL, AUTO, or ADAPTIVE).
In the
"MANUAL" mode, purge operation is continuous, whether chiller is on or off. The "MANUAL"
mode is recommended only for service procedures.
In the
"AUTO" mode purge operation interlocks with a chiller-generated "cooling/run" signal which
provides a run signal to the purge unit’s microprocessor control. Operation In the "AUTO” mode is
identical to the “ADAPTIVE” mode except operation occurs only while the chiller is running.
In the
“ADAPTIVE” mode, the purge system operates in a “self-learning” and “self-adjusting” duty
cycle mode, based upon previous non-condensable pumpout history. Purge operation is
independent of the operational status of the chiller, and will Duty Cycle (start and stop purging
activity as needed) whether the chiller is running or not.
“AUTO” MODE IS THE RECOMMENDED NORMAL OPERATING MODE
Security-Lock
The purge unit is equipped with a simple security lock system that prevents unauthorized
personnel from tampering with certain functions. The purge unit comes from the factory with the
security lock enabled (see Dip switch S1 settings starting on page 28).
NOTE :
SYSTEM IS NOW OPERATIONAL , if you desire any other activity or understanding of the
many capabilities such as diagnostics, sensor readings and interpretation of accumulated
data, you must familiarize yourself with the rest of this manual. Purge operation will now be
automatic. If you desire to Change one or more of the pre-set factory default settings see
Setting Operational Parameters on page 26.
NOTE:
The purge’s microprocessor has been pre-programmed with certain PRESET DEFAULTS for
each operational parameter setting. The purge will automatically default to those factory
preset operating parameters unless changed by the operator. If you are relying upon Quick
Start, the following pre-set parameters will apply.
“PURGE FAULT” - Preset default 30 minutes (If non-condensable pumpout activity in a 24
hour period exceeds 30 minutes the purge will shut down)
“FAULT Bypass” - Preset default 4 hours, FAULT BYPASS overrides “PURGE FAULT”
setting for the amount of time set in the FAULT Bypass setting (active only when the
BYPASS keypad switch is pressed) For more information, see SETTING OPERATIONAL
PARAMETERS on page 26.
“DRAIN CYCLE” - Preset default 10 seconds (this time delay sets the make-break hysterisis
of liquid level switch LS1).
