EEPROM data check failure(data beyond limit, reverse sequence
etc.)
Tdi / Td1≥130°C (E). Stop and alarm if it is over the set value for 2
secs continuously at interval of 25msec.
Discharging temp. over
Resume automatically if the discharging temp. is 10 degree lower
heat protection (Tdi)
than the alarm condition after stopped for 3 mins.
Four times an hour, failure confirmed.
Reversion is successful if the following condition is satisfied for
continuous 10 secs after 4WV is electrified for 3 mins.
4WV reversing failure
If not satisfied, protect and stop.
(Tao>-10°C, β=0.60; Tao≤-10°C, β=0.40)
* 4WV OFF restart after 3 mins
* Thermo. OFF for 2 times continuously, Error and stop
Master unit checks heating mode operation. If some slave units'
4WV reversing failure 4WV still can't electrified after starting up for 20 mins, failure 35-1
is shown.
Normally in operation (excluding startup, deforest, oil return, remains,
stop), detect Toil < CT+10°C for continuous 5 mins, stop and alarm.
Oil temp. sub-cooling
Resume automatically after 170 secs; Lock if alarming three times an
protection (Toili)
hour.
The same as Td sub-cooling protection
