LP
message if a malfunction is detected when the installation is started up
using the pump down manoeuvre. (See page 17).
DOES NOT
activate the alarm relay or the sound alarm, it is only shown on the display.
Compressor safety chain alarm
The ASC message is displayed if any component in the compressor's safety chain is triggered
(compressor motor guard, thermistors or high pressure controller). Regulation is stopped until
protection has been restored.
Alarm delay
These delays prevent the display of specific alarms while allowing the unit to recover normal
operation after certain events.
-Start-up delays (
A3
): Delays activation of temperature alarms on power-up (start-up or after a power failure).
This allows avoiding continuous alarms upon start-up
-Delay after defrost (
A4
): Delays activation of temperature alarms post-defrost.
-Delay of max/min temperature alarm (
A5
): Delays activation of maximum (
A1
) and minimum (
A2
) temperature
alarms from the moment temperature probe 1 reaches the set value.
-Delay of external alarm activation (
A6
): Delays the activation of the external alarm from the moment the digital
input becomes active.
-Delay of external alarm deactivation (
A7
): Delays the deactivation of the external alarm from the moment the
digital input becomes inactive.
-Door opening alarm relay (
A12
): Delays activation of the open door opening detection alarm.
Alarm relay configuration
If the auxiliary relay 2 is configured as an alarm relay (
P62
=1), parameter
A9
allows defining the status of the relay
when an alarm is triggered.
Ÿ
A9=0 relay active (ON) in case of alarm (no alarm OFF)
Ÿ
A9=1 Inactive relay (OFF) in case of alarm (no alarm ON)
9.7.- Access code (password)
It allows protecting the configuration of the unit using a 2 digit code (from 01 to 99). If it is active a code is requested
when you try to access the programming menu. This menu cannot be accessed if a wrong value is entered. The code is
defined using the
L5
parameter.
Parameter
P2
defines the operation of this code.
