HACCP alarm
The alarm is activated should situations be detected which could endanger the integrity of
the products stored in the cold room.
If the temperature of the cold room is higher than that defined in parameter h1 for a
length of time exceeding that defined in parameter h2, the alarm activates, displaying the message HCP on screen.
Upon pressing the mute key, the sound alarm switches off, but the alarm remains.
Once the temperature drops below parameter h1, if the mute key has been pressed, the alarm disappears. If the
mute key has not been pressed, the audible alarm deactivates but the HACCP indicator remains in flashing mode,
indicating than a non-confirmed HACCP alarm has occurred.
Press the mute key to confirm an HACCP alarm.
Sensor error alarm
If one of the enabled probes is crossed, open circuit, or out of range, the message
E1, E2, E3, E4, E5 or E6 is displayed depending on whether it is sensor S1, S2,
S3, S4, S5 or S6.
Open door alarm
The door has been open for a longer time than defined in parameter A12, the open door
alarm is activated.
In order to detect the open door, configuration is required of one of the digital inputs as
“door contact” (l10 or l20=1).
Activates alarm relay and audible alarm.
Minimum superheat alarm
If the superheat value falls below the value defined in parameter A20, the alarm is
activated and the display shows the message LSH.
The alarm disappears when the value A20 + differential A22 is reached.
Parameter A21 allows a delay in the activation of this alarm to be defined.
Activates the alarm relay and the audible alarm.
Maximum evaporating pressure alarm
If the evaporating pressure exceeds the value defined in parameter A26, the alarm is
activated and the display shows the message MOP
.
The alarm disappears when the value A26 + differential A28 is reached.
Parameter A27 allows a delay in the activation of this alarm to be defined.
Activates the alarm relay and the audible alarm.
Minimum evaporating pressure alarm
If the evaporating pressure falls below the value defined in parameter A29, the alarm is
activated and the display shows the message LOP
.
The alarm disappears when the value A29 - A31 is reached.
Parameter A30 allows a delay in the activation of this alarm to be defined.
