11.2 If (Pressure switch ==Reset)
continue, else indicate NOT
DRAINING error.
11.3 FAN + DRAIN
12 FAN
Test Complete.
Notes:
1. Rotary models do not have any of the specific indicator
LEDs mentioned. For rotary models, the only indication of
progress from one major step to another is the buzzer
sounding for 0.5 seconds at the start of each major step,
where indicated.
2. If a fault is detected during the test cycle, then the
controller will: Stop the test; Shutdown all outputs; Sound
the buzzer continuously; Immediately indicate the fault
using the same indication method as described in section
4 FAULT INDICATION, (note fault codes will not be stored);
Then wait for the Start/Cancel button to be pressed, at
which time the buzzer will be silenced.
3. On Push-button control models, pressing the Water Temp
Button is to hold the outputs on in the current step, (except
for the "LED and Button Test", and filling steps where a 3
minute time limit exists in order to prevent flooding).
Pressing Water Temp Button again will allow progression.
4. On Rotary control models, Turning the HEAT OPTIONS
knob such that the position indicator is pointing towards
the Heat Options LED, will cause the control to hold the
outputs on in the current step, (except for filling steps
where a 3 minute time limit exists in order to prevent
flooding). Turning the HEAT OPTIONS knob such that the
knob is horizontal with the position indicator is pointing
away from the Start/Cancel button again, will allow the test
to progress again.
ACTION TIME / Sec
60 The buzzer will sound for 0.5 seconds at the
start of the step.
The Smart or Heated Dry LED will be on.
Max 20 The buzzer will sound for 0.5 seconds at the
minutes start of the step.
The Water Temp Normal LED will be on.
30 The buzzer will sound for 0.5 seconds at the
start of the step.
The Water Temp Hot or Sani LED will be on.
20 The buzzer will sound for 0.5 seconds at the
start of the step.
The Delay Start 2hr LED will be on.
n/a The Delay Start 2hr LED will be on.
30 The Delay Start 2hr LED will be on.
40 The buzzer will sound for 0.5 seconds at the
start of the step.
The Delay Start 4hr LED will be on.
n/a The buzzer will sound for 0.5 seconds.
CLEAN LED is on.
5. On Push-button control models, pressing the Delay Start
button is to advance the control into the next step, except
during the Model Identification, and LED and Button Test
steps.
6. On Rotary control models, Turning the WASH CYCLES
knob so it is horizontal with the position indicator pointing
away from the Start/Cancel button, and then turning the
WASH CYCLES knob so the position indicator is pointing
towards the Wash Cycles LED, will cause the control to
advance into the next cycle step, except during the Model
Identification, LED Test and drain steps. To advance the
test again, this sequence must be repeated.
7. Pressing and holding down the Start/Cancel button for 3
seconds at any stage, (including if a fault has been
detected), is to return the control to the stand-by state, by
turning off all LEDs, then draining until 45 seconds after
the 1st level pressure switch detects empty, (or for 30
seconds if empty was detected when draining started).
The last used Wash program and Option LEDs will flash
during the pump out period.
Buzzer silencing mode has no effect during this mode.
