Alarm delays
These delays prevent certain alarms from being shown, to allow the installation to recover its normal operation after
certain events.
• Delays in start-up (A3): This delays the activation of the temperature alarms upon receiving power (at start-
up or after a power supply failure) or when exiting Stand-by mode. This allows for the installation to start up
avoiding alarms.
• Delay after a defrost (A4): This delays the activation of the temperature alarms when a defrost completes.
• Maximum and minimum temperature alarm delay (A5): This delays the activation of the maximum (A1) and
minimum (A2) temperature alarms, from when the temperature in sensor 1 reaches the programmed value.
• Delay to activation of external alarm (A6): This delays the activation of the external alarm, from when the digital
input becomes active.
• Delay to deactivation of external alarm (A7): This delays the deactivation of the external alarm, from when the
digital input becomes active.
• Delay to activation of open door alarm (A12): Delays activation of the open door alarm.
• Delay to activation of LSH alarm (A21): Delays activation of the low superheat alarm from when the pro-
grammed value is reached.
• Delay to activation of MOP alarm (A26): Delays activation of the maximum operating pressure alarm from
when the programmed value is reached.
• Delay to activation of LOP alarm (A30): Delays activation of the lowest operating pressure alarm from when
the programmed value is reached.
Alarm relay configuration
Should any relay have been configured as an alarm relay, parameter A9 allows for the relay status to be defined
when an alarm is triggered:
A9=0 Relay active (ON) in the event of an alarm (OFF without alarm)
A9=1
Relay inactive (OFF) in the event of an alarm (ON without alarm)
Alerts
The device alerts the user through an on-screen message when an event occurs which requires
his/her attention. However, it does not activate the sound alarm or the alarm relay (if active).
Defrost time-out alert
The message Adt is displayed when a defrost has completed due to time-out, if parameter A8=1.
Pump down malfunction error (stop)
The message Pd is displayed if a malfunction is detected when the installation is stopped using
the pump down manoeuvre. (See page 19).
Pump down malfunction error (start-up)
Displays the LP message if a malfunction is detected when the installation is started up using the
pump down manoeuvre. (See page 19).
Maximum overheating alert
If the superheat value falls below the value defined in parameter A23, the and the display shows the message HSH.
The alert disappears when the value A23 - A25 is reached.
Parameter A23 allows a delay in the activation of this alarm to be defined.
