12.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY (DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the Controller ON.
3. Automatically the parameter list of the “Hot Key” is downloaded into the Controller memory, the “doL” message is blinking followed a by
flashing “End”.
4. After 10 seconds the instrument will restart working with the new parameters.
5. Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and then on if you want to restart the download again or
remove the “Hot key” to abort the operation.
13. ALARM SIGNALS
Message Cause Outputs
“P1” Thermostat probe failure Alarm output ON; Compressor output according to parameters “COn” and “COF”
“P2” Evaporator probe failure Alarm output ON; Other outputs unchanged
“P3” Auxiliary probe failure Alarm output ON;
Other outputs unchanged
“HA” Max. temperature alarm Alarm output ON; Other outputs unchanged
“LA” Min. temperature alarm Alarm output ON; Other outputs unchanged
“EE” Data or memory failure Alarm output ON; Other outputs unchanged
“dA” Door switch alarm Alarm output ON; Other outputs unchanged
“EAL” External alarm Alarm output ON; Other outputs unchanged
“BAL” Serious external alarm Alarm output ON; Other outputs OFF
“PAL” Pressure switch alarm Alarm output ON; Other outputs OFF
PAn “Panic” Alarm Alarm output ON; Other outputs unchanged
“rtc” Real time clock alarm Alarm output ON; Other outputs unchanged; Defrosts according to par. “IdF”
The alarm message is displayed until the alarm condition is recovery.
All the alarm messages are showed alternating with the room temperature except for the “P1” which is flashing.
To reset the “EE” alarm and restart the normal functioning press any key, the “rSt” message is displayed for about 3s.
13.1 SILENCING BUZZER / ALARM RELAY OUTPUT
If “tbA = y”, once the alarm signal is detected the buzzer and the relay are is silenced by pressing any key.
If “tbA = n”, only the buzzer is silenced while the alarm relay is on until the alarm condition recovers.
13.2 “EE” ALARM
The
dIXEL
instruments are provided with an internal check for the data integrity. Alarm “EE” flashes when a failure in the memory data occurs. In
such cases the alarm output is enabled.
13.3 ALARM RECOVERY
Probe alarms : “P1” (probe1 faulty), “P2” and “P3”; they automatically stop 10s after the probe restarts normal operation. Check connections before
replacing the probe.
Temperature alarms “HA” and “LA” automatically stop as soon as the thermostat temperature returns to normal values or when the defrost starts.
Door switch alarm “dA” stop as soon as the door is closed.
External alarms “EAL”, “BAL” stop as soon as the external digital input is disabled “PAL” alarm is recovered by switching OFF the instrument.
