General alarm
Input from AI3 Leads to shut down of IPS 8
Fault in system connected to the DIO4
Input from AI3 Leads to shut down of IPS 9
E01
Temp Sensor Fault
Indicates no signal from temperature sensor
(R452a)
Broken wire to R452a temperature sensor
Repair temperature sensor wire or replace
temperature sensor
E01
Temp Sensor Fault
Indicates no signal from temperature sensor
(R452a)
Electrical supply failure supplying R452a
temperature sensor
Repair or replace power source
E01
Temp Sensor Fault
Indicates no signal from temperature sensor
(R452a)
Temperature measurement of the R452a line
is out of range
Compare temperature with another
temperature sensor reading and replace
temperature sensor if needed
E02
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R452a)
Broken wire to R452A pressure transmitter
Repair pressure transmitter wire or replace
pressure transmitter
E02
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R452a)
Electrical supply failure to the R422a pressure
transmitter
Repair or replace power source
E02
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R452a)
Pressure measurement of the R452a line is out
of range
Compare pressure with another pressure
reading and replace pressure transmitter if
needed
E03
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R717)
Broken wire to R717 pressure transmitter
Repair pressure transmitter wire or replace
pressure transmitter
E03
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R717)
Electrical supply failure to the R717 pressure
transmitter
Repair or replace power source
E03
BPL Sensor Fault
Indicates no signal from pressure transmitter
(R717)
Pressure measurement of the R717 line is out
of range
Compare pressure with another pressure
reading and replace pressure transmitter if
needed
E04
Low temperature
Indicates too low ambient temperature
(<-10 °C)
Too low ambient temperature
Move the IPS to a higher ambient temperature
E05
High temperature
Indicates too high ambient temperature
(>120 °C)
Too high ambient temperature
Move the IPS to a lower ambient temperature
E05
High temperature
Low R452a charge because of possible leak
Locate and repair leak Evacuate
Move the IPS to a lower ambient temperature
E06
Low pressure BPL
Indicates too low R717 pressure
Closed stop valve
Open inlet stop valve
E07
High pressure BPL
Indicates too high R717 pressure
Ammonia system pressure too high
Wait for lower pressure
E08
Low pressure BPH
Indicates too low R452a pressure
Low R452A charge
Find and repair leak, evacuate and recharge
with R452a
E09
High pressure BPH
Indicates too high R452a pressure
R452s system pressure too high
Wait for lower pressure
E10
System is OFF
Indicates status of the main switch
Main switch is OFF
Switch ON the main switch
E11
Memory is full
A memory reset is required
Memory is full from long time operation
Clean MCX memory by means of finding
Parameters_UnitConfig_
E12
Totla purge time error
This occurs when PLT is activated System will
automatically restart when CST has expired
Restrictor is blocked
Replace the restrictor
E13
Compressor ERROR
Indicates no status is being received from
relay KL01
Possible broken wire from the MCX
Repair broken wire from the MCX
E14
Liquid alarm
Signal from the LLS that there is liquid in the
evaporator
E15
Memory wrong!
Wrong counter values The unit will
automatically repair itself
E16
Discharge sensor error Indicates no signal from temperature sensor
E17
Suction sensor error
Indicates no signal from temperature sensor
