Section I V– Operating Procedures
MENU 03: Display Units and Model Type.
LED 1: Selects the Pressure display in PSIG or
BAR.
LED 2: Selects the Temperature Display in 'F or
'C.
LED 4: Selects Compressor Model : QSF or
QSB/QMB.
LED 6: Reset or Preset the Running Hours.
LED 7: Sets the I.D. of the compressor. This is
used in the Networked control option (future
product).
As before, the setting is 'taken' when the display reading is steady.
Faults:
1) EMERGENCY STOP: Pressing this button will cause the immediate halting of compressor operation.
This is a redundant control; the microcontroller is signaled to halt operations and power is removed from
all control relays, causing all circuits to open up. The LED indicators at the side of the panel will flash and
'STOP' will flash on the numeric display.
To reset, twist the stop button to release from the latched condition and press the RESET control button.
The redundant over-temperature HAT switch will also trip the same way as the EMERGENCY STOP, as
it is part of the same circuit. This will trip if the discharge temperature exceeds the pre-set point. In this
case, the emergency stop button is NOT engaged, and the display may be cleared with the RESET
button.
2) CONTACTOR FAULT: The side LED's will flash if the main contactor fails to close properly or fails to
open in a controlled shutdown ( Motor OL/Fault LED ).
LED & Message Indicators:
1) Excessive pressure Error: Top LED flashes fast.
2) Separator Element clogged: Second LED flashes slowly.
3) Air Filter Clogged: Third LED Flashes slowly.
4) Air Filter timer expired: Third LED is steady, and message 'AIRF' flashes on the display.
5) Excessive Temperature: Fourth LED flashes slowly.
6) Temperature error (broken wire etc.): Fourth LED flashes fast.
7) Fluid Filter clogged: Fifth LED flashes slowly.
8) Fluid timer expired: Fifth LED is steady, and message 'FLUI' flashes on the display.
9) Motor Overload: Sixth LED flashes fast.
10) Power line glitches ( loss of cycles > 40ms ), left 3 bars in the display flash, possible problems in the 3
phase power supply.
