General error codes display
For common errors, scheme 3 is used: during the first phase it indicates an „E“ on the
left (21), an „ r” on the right (23) and in the second phase it indicates the two-digit error
number.

Temperature on TC board over 95 degrees (displays 5 sec).
Temperature on power board over 100 degrees (displays 5
sec).
Power board NTC (P1< 2,18V (80C), no error indication). P2<

Er26
Relay voltage too high when switched off or too low when
switched on (PWM feed back voltage).
When TC is off : voltage > 2,46V.
When TC is on and PWM off : voltage < 2,46V.
When TC is on and PWM on : voltage > 2,46V.
