Pressure
The digital display shows the current output pressure in PSIG or kPa. The output
pressure is adjusted by pulling the regulator knob out and turning it. Push the knob in to
lock the pressure setting.
Converter Temperature
The current converter temperature can be shown on the digital display by pressing and
holding the “Converter Temperature” button. The set point is adjusted at the factory
using jumpers located on the power supply board.
Status LEDs
Converter Ready: The converter ready light on the front panel remains red while the
instrument warms up. This light turns green when the instrument is warmed up within 90
percent of set point temperature.
Standby:
The standby light indicates that the pump is shut down. This mode
minimizes wear on the compressor and conserves the scrubbing desiccants while
eliminating the normal warm-up period. This mode can only be initiated via a grounding
signal sent to the connector on the rear panel a from an external data system (computer or
PLC).
Service Alarm: When the service alarm activates, it indicates that a preset service
interval has elapsed and that the adsorbent scrubbers may need to be changed. The preset
service interval is set for 90 days at the factory and can be changed using jumpers located
on the Display Board. The Display Board is attached to the inside of the front panel (see
Figure 3-2). The Service Reset button, which is also located on the Display Board, sets
the elapsed time back to zero. It should be noted that the elapsed time is retained in
battery-backed memory when the unit’s main power is turned off, but the service clock
only increments when the unit is actually in use.
