MONITORING SYSTEM
ALARMS
If faults occur during normal machine operation, the controller will stop the machine and display the code of the
alarm relative to the activated safety device. After having checked the alarm and eliminated its cause, the user can
reset the controller by pressing the on/off key.
1. How to reset the alarms
The screen-printed design illustrates, with cyclic rotation, what happens when the on/off key is pressed. As pre-
viously described, the key carries out two separate functions. If pressed for 1 second, it acts as an "alarm reset";
if pressed for 2 seconds, it "turns the controller on and off".
2. Alarm codes
The following diagram lists the alarm codes, the relative international identifying symbol and the description of the
type of alarm. Two alarm codes are cumulative, i.e. they have several meanings. All the other alarms have only one
meaning. Pay particular attention to code E00 since this is not an alarm that denotes a malfunction but signals that
the remote on/off switch or the off command of the unit controlled by the programmer clock (accessory) have been
activated.
E00 : Machine in stand-by status by means of the remote control
E01 : Activation of the maximum pressure switch
E01 : Activation of the thermic in the compressor
E01 : Activation of the power line phase presence and sequence monitoring device (if installed)
E01 : Activation of the temperature probe in the compressor delivery pipe (if installed)
E02 : Activation of the minimum pressure switch
E04 : Activation of the phase sequence control (only for threephase units)
(1)
E05 : Activation of the antifreeze safety procedure
E06 : Exchanger outlet water temperature probe faulty
E07 : Faulty battery probe
E40 : Exchanger inlet water temperature probe faulty
E41 : Water pump thermic activated (if applicable)
E41 : Activation of differential water pressure switch on the plate exchanger
(1)
WARNING: Jumper the relative terminals to inhibit the function.
DESCRIPTION
DISPLAY
If a fault occurs, the controller will signal the activated alarm code by
means of a flashing message on the display.
Press the on/off key for 1 second to reset the controller and allow the unit
to operate normally again.
