Program will not HALT.
•
Program not IN CYCLE (small square symbol not flashing in display).
•
Program must be RUNNING for HALT to occur.
Program will not RESET.
•
Program status must be HALTED before RESET is possible.
FLOOR MOUNTED MODELS ONLY:
Distilled water tank will not fill:
•
Distilled Water isolation hand valve closed from water still.
•
No distilled water supply to machine.
•
Distilled water fill solenoid valve not operating. See previous notes for checking
outputs and finding fuses. While observing DIAG1 display, move float switch up
and down. Input status is the same as for the upper level switch for the bath.
•
Level switch stuck in high level position.
•
Distilled water pressure too high (not gravity fed) for solenoid valve rating. If distilled
water pressure too high, solenoid valve cannot open.
CAUTION:
S/Valve coil can
burn out.
NOTE:: For systems with pressurised distilled water, IEC can fit a higher
pressure solenoid valve in the distilled water circuit.
Will not dispense distilled water OR slow dispensing.
•
Manual D/W volume set to ON but d/w volume set to small volume. See D/W
CONTROL display.
CAUTION: If the manual distilled water volume is set to a value and is ON, this
volume will override any volume set in the programs. All dispenses will be this
Manual Volume.
•
Dispensing solenoid valve not operating. Blown output fuse. See previous notes for
checking outputs and finding fuses.
•
If dispensing very low pressure, motor not running fast enough. When dispensing
switch is pressed, drive to motor should be at #4000. See DIAG2 display for the
drive speed value.
•
Faulty press switch on dispensing gun or open circuit wiring from gun to PLC. See
DIAG1 display to check inputs. To prove faulty gun switch or wiring, press
simulated gun switch in D/W CONTROL display.
•
Jammed dispensing pump motor or pump rubbing internally.
•
Cone forming nozzle on front of dispensing gun jammed shut.
•
Faulty distilled water circulating and dispensing pump under rear cover.
•
Strainer inside distilled water tank requiring cleaning. This is a Y shaped device with
a sealed removable cap to examine the strainer gauze.
