10.2 Types of alarms
The iJW controller can display two types of malfunctions:
• warning, when this type of error occurs, the alarm code is shown on the display, alternating with the main value, and the
“Service” icon is shown on the display, however the buzzer does not sound, no relay is activated; some signals fall under
this category, e.g. defrost ended due to maximum time, dirty condenser, anomalous temperature alarms, confi guration errors.
• alarms, when this type of error occurs, the alarm code is shown on the display, alternating with the main value, and the “Ser-
vice” icon comes on, the buzzer fl ashes and the relay is activated; this category includes alarms for which with the relay is
confi gured as an alarm, probe errors, temperature alarms, frost protection, communication errors with the VCC compressor,
power supply over and under voltage, etc.
Notice:
• the digital outputs can be confi gured to signal the alarm status, normally open or normally closed. See “Digital outputs”.
• An alarm can also be activated from an external contact, immediate or delayed. See “Digital inputs”.
The warning and alarm signals can be immediate or delayed by parameter (see the Alarm table).
Both warnings and alarms can be reset automatically, manually or semi-automatically:
• automatic, when the cause is no longer present, the alarm also ceases;
• manual, when the cause is no longer present, the alarm remains active until manually reset by parameter;
• semi-automatic, reset is automatic 3 times in an hour, after which manual reset is required.
Active alarms are signalled by the buzzer (see parameter Hb) and the fl ashing of the “Service” icon
. The alarm code is shown
on the display, alternating with the main value. Pressing any button mutes the buzzer. If more than one error occurs, these are
displayed in sequence. When an alarm is cleared, it is stored in the alarm log containing a maximum of fi ve alarms, in a FIFO
list (the 6th alarm overwrites the 1st alarm, and so on). The error log can be accessed from the user terminal, via supervisor or
Applica app (Bluetooth™ connection only).
Example
Display after HI error.
Fig. 10.a
The alarms can be reset manually using parameter rSA, from the user terminal or Applica Desktop confi guration software, or in
Applica (Bluetooth™ connection only) using the specifi c command on the Alarms page (“Service” or “Manufacturer” level access
is required). If the condition that generated the alarm is still present, the alarm will be reactivated after resetting.
The alarm log can be deleted using parameter rAL, accessible from the user terminal, Applica Desktop confi guration software
or in Applica (Bluetooth™ connection only) using the specifi c command on the Alarms page (“Service” or “Manufacturer” level
access is required).
Notice: deleting the alarm log is irreversible.
