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 open door alarm (A12): this delays the activation of the alarm upon detecting that the door is open.
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 17).
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 17).
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.
Light control
The AUX 1 or AUX 2 relay must be configured as “Light” (o00, o10 or o20=2).
Switching the lights on or off is controlled using:
• The LIGHT push-button : one press switches the lights on or off.
•
The cold room door:
when the door is opened, the lights remain on for the time defined by parameter b01.
If the value is 0, when the door closes the lights go out. (One of the digital inputs must be configured as door
contact (I10, I20 or I30=1). The control even occurs with the equipment in Stand-by.
