Ir96: Alarms; Dimensions - Carel IR32M Manual

FLASHING LED: actuator set delay
Insertion of the relative function is delayed for a period while awaiting an external consent or while held up
by another process still in progress.
TEMPERATURE FLASHING: door open or door switch broken.
Close the door or control the door switch.
E0 FLASHING: control sensor error
Sensor not compatible with the equipment; sensor cable interrupted or short circuit.
Faulty sensor: disconnect the sensor from the instrument and measure the resistance (NTC: 0ºC=27K
Ohms)
E1 FLASHING: evaporator sensor error
Sensor not compatible with the equipment; sensor cable interrupted or short circuit.
Faulty sensor: disconnect the sensor from the instrument and measure the resistance (NTC: 0ºC=27KΩ)
IA FLASHING: alarm from digital input
Check 'Multi-function' inputs and parameters A4 and A5
Ad FLASHING: delayed alarm from digital input
Check 'Multi-function' inputs and parameters A4, A5 and A7
LO FLASHING: low temperature alarm (temperature lower than SET-AL-A0)
Check parameters AL, Ad and A0
The alarm will cease as soon as the temperature returns within the limits selected.
HI FLASHING: high temperature alarm (temperature higher than SET +AH + A0)
Check parameters AH, Ad and A0
The alarm will cease as soon as the temperature returns within the limits selected.
EA, EB, EE: data acquisition error. RESET procedure
In order to restore normal working conditions, reset the default value of the parameters with this procedure:
•
turn off the instrument;
•
press the PRG button and, keeping it pressed, turn on the controller;
•
the display shows "-c-";
•
after a few seconds, the instrument enters the RESET procedure and allows the modification of parameters. (*)
•
should EE persist, press the button
(*) Any modification made before the reset procedure will be lost
Ed FLASHING: defrost end by timeout
•
check parameters dt, dP and d4
•
check effectiveness of the defrost
•
in case inhibit the alarm Ed through the r3 parameter
dF FLASHING: defrosting in progress
This is not an alarm signal, but it indicates that the instrument is carrying out a defrost. Appears only if
parameter d6=0.
