14 Protection Control
14.1. Protection Control For All Operations
14.1.1.
Restart Control (Time Delay Safety Control)
• The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on again by
pressing OFF/ON button at remote control within this period.
• This control is not applicable if the power supply is cut off and on again.
• This phenomenon is to balance the pressure inside the refrigerant cycle.
14.1.2.
30 Seconds Forced Operation
• Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation although the intake air
temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON button at the remote control
is permitted or the Auto OFF/ON button at indoor unit.
• The reason for the compressor to force operation for minimum 30 seconds is to allow the refrigerant oil run in a full cycle and
return back to the outdoor unit.
14.1.3.
Total Running Current Control
1. When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation will be
decreased.
2. If the running current does not exceed X value for 5 seconds, the frequency instructed will be increased.
3. However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for 3 minutes.
4. The first 30 minutes of cooling operation, (A) will be applied.
14.1.4.
IPM (Power transistor) Prevention Control
A. Overheating Prevention Control
1.When the IPM temperature rises to 120°C (E7~15LK) and 110°C (E18~21LK), compressor operation will stop immediately.
2.Compressor operation restarts after 3 minutes the temperature decreases to 110°C (E7~15LK) and 95°C (E18~21LK).
3.If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).
B. DC Peak Current Control
1. When electric current to IPM exceeds set value of 18.5 A (E7 ~ 15LK) and 30.0 ± 5.0A (E18 ~ 21LK), the compressor will
stop operate. Then, operation will restart after 3 minutes.
2. If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will restart after 2
minutes.
3. If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after 1 minute. If
this condition repeats continuously for 7 times, all indoor and outdoor relays will be cut off, timer LED will be blinking (“F99”
is indicated).
