• i59
code: WP current read ADC - fault
•
Alarm is set if there is detected a fault in the current reading chain on MCB;
incl. ADC conversion.
•
It´s verified by the current sum of the three motor phases which should be
nearly zero; if the sum is higher than 40mA for longer than 300 ms than the
assumption is that something is wrong.
• i5A
code: Over temp or Overload
This code has different meaning depending on platform.
DIVA2 specific
•
Internal warning is set when the internal calculations based on the
measured currents lets expect that the temperature are out of standard
limits (200° C – with 40° C margin due to measurement and calculation
tolerances).
•
The threshold value for the warning is 200 – 70 (max. ambient temperature
inside the dishwasher) - 10 (activation margin) = 120° C
given.
•
If the warning is set, than the motor is stopped and a new winding
resistance calculation is performed. In this way the real temperature can be
calculated – temp. calculation is based on ref. resistance of motor windings
at 22° C.
- the alarm is set if the value is greater than the threshold 178° C (200
– 22).
rem.: the alarm is reset by MCB after verification procedure with
baseboard.
PB100 specific
•
Alarm is set if load is 0.68 A for 10 s for the wash pump or 0.55 A for 10 s
for the drain pump.

Alarm Codes
• i5B (i5H)
•
Alarm is set if currents are not changing within 2.5 s with less than 0.0275
A for WP.
•
Alarm is set if currents are not changing within 0.5 s with less than 0.03363
A for DP.
•
"B" may be displayed as "H" in the 7-segment display
• i5C
•
Hardware supervising – will be set when abnormal high current of about
0.7 amps are detected.
• i5D
•
Alarm will be set when the current is detected higher than the max allowed
current of 0.550 A
warning level is
• i5E
•
Alarm will be set when the motor blocked condition is detected during start
of motor and also during the running motor; reasons can be dirt, too high
load, mechanical problems on impeller.
• i5F
•
Alarm will be set if motor connection is detected wrong based on motor
currents measurements. If currents are inside the thresholds (+/- 22 mA);
debounce is set to 1.6 seconds
•
This code is also possible if a phase is detached or if a winding inside the
motor is broken.
