Toshiba RAV-SM1104UT-E Current release value shift control, Over-current protective control

7.Current release value shift control

1)This control purposes to prevent troubles of the electronic parts such as the compressor driving elements and the compressor during cooling operation.

2)The current release control value (I1) is selected from the following table according to TO sensor value.

Current release control value (11)

[A]

Temperature range	SP110, SP140
44°C ≤ To	15.0
39°C ≤ To < 44°C	17.7
To < 39°C	20.0
TO error	15.0

8.Over-current protective control

1)When the over-current protective circuit detected an abnormal current, stop the compressor.

2)The compressor restarts after 2 minutes 30 seconds setting [1] as an error count.

3)When the error count [8] was found, determine an error and restart operation is not performed.

4)For the error display contents, confirm on the check code list.

9.High-pressure release control

1)The operation frequency is controlled to restrain abnormal rising of high pressure by TL sensor in cooling operation and TC sensor in heating operation.

2)When TL sensor in cooling operation or TC sensor in heating operation detects abnormal temperature of the stop zone, stop the compressor and the error count becomes +1.

3)When the compressor stopped with 2), the operation restarts from the point of the normal operation zone (e point or lower) where it returned after 2 minutes 30 seconds.

4)The error count when the compressor stopped with 2) is cleared after the operation continued for 10 minutes. If the error count becomes [10] without clearing, the error is determined and reactivation is not performed.

5)For the error display contents, confirm on the check code list.
