Over-current preventive control | Toshiba RAV-SM560AT-E specs

NOTIFICATION

It is not an abnormal phenomenon that electro-noise may be heard while heating the coil.

4. Short intermittent operation preventive control

QThe compressor may not stop for preventing the compressor for 3 to 10 minutes after start of the operation even if Thermo-OFF signal has been received from the indoor. This phenomenon is not abnormal. (Continuous operation time of the compressor differs according to the operating status.)

RIf the equipment is stopped from the remote controller, the operation does not continue.

5.High-voltage suppression TE control (Only for SM800)

QThis control suppresses that voltage becomes abnormally higher during cooling operation.

RStop the compressor under condition of TE ≥ 67°C, and count 1 on the error count.

SAfter 2 minutes 30 seconds passed, if TE < 67°C, the compressor restarts and the error count is cleared when the operation continues for 10 minutes.

TWhen TE ≥ 67°C is detected again within 10 minutes, 1 is added to the error count and restart is repeated.

UIf the error counts 10 are recognized, it is determined as an error and restart is not performed. Error code ‘P04’ is displayed.

VAfter restarting the compressor, continue controlling by using 70% to 90% of the control value of the current release control for minimum 30 minutes.

6.Over-current preventive control

QThis control function stops the compressor when over-current preventive circuit has detected an abnormal current.

RThe compressor restarts with error count 1 after 2 minutes 30 seconds.

SIf the error counts 4 are recognized, it is determined as an error and restart is not performed. Error code ‘H01’, ‘H02’ or ‘P26’ is displayed.

7.Current release value shift control

1)Object: SM800

QThis control function prevents troubles of the electron parts such as G-Tr of inverter of compressor drive system and troubles of the compressor during cooling operation.

RThis control function corrects the current release control value (1) in item 3 of 9-2-2 by TO sensor value.

SThe value to be corrected is based upon the following control diagram and correction value table.
