DATA PRINTING
6.1
Introductory information
The device has a serial port for communicating with the PM 100A
X9S001 print module.
6.2
Connecting the PM 100A X9S001 print module
Connecting the PM 100A X9S001 print module:
• ensure that parameter P71 is set to 1
• ensure that the print module baud rate is set to 9,600 baud
• ensure that the module parity is set to odd.
6.3
Printing operational cycle information
Printing operational cycle information:
• operational cycle start date
• operational cycle or program type (or one of the codes listed in the
table below)

Consequences:
• the operational cycle will be interrupted
• the loads will be switched off
• it will not be possible to start any operational cycles
• the alarm output will be activated
Er1
Evaporator probe error
Remedies:
• the same as for the previous case, but in relation to the
evaporator probe
Consequences:
• defrosting will last for the length of time set by parameter
P24
• the evaporator fan will be switched off during storage
• the alarm output will be activated
Er3
Needle probe error
Remedies:
• the same as for the previous case, but in relation to the
needle probe
Consequences:
• if a set-temperature chilling or freezing operation is
ongoing, the operational cycle will be interrupted
• it will not be possible to start any set-temperature
operational cycles
• the alarm output will be activated
Er4
Condenser probe error
Remedies:
• the same as for the previous case, but in relation to the
condenser probe
Consequences:
• the condenser fan will operate in parallel with the
compressor, except when set by parameter P54
• the alarm output will be activated
Err
User interface-module communication error
Remedies:
• check the user interface-module connection
Consequences:
• if an operational cycle is ongoing, the device will continue
to function normally
