13 ALARM SIGNALS
Message Cause
P1
Thermostat probe failure
P2
Evaporator probe failure
P3
Probe 3 probe failure
P4
Probe 4 probe failure
HA
Maximum temperature alarm
LA
Minimum temperature alarm
HA2
Condenser high temperature
LA2
Condenser low temperature
dA
Door open
EA
External alarm
CA
Serious external alarm (i1F=bAL) All outputs OFF.
CA
Pressure switch alarm (i1F=PAL) All outputs OFF
EE
Data or memory failure
The alarm message is displayed until the alarm condition is recovered.
All the alarm messages are shown 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 3 sec.
13.1 SILENCING BUZZER
Once the alarm signal is detected the buzzer can be silenced by pressing any key. Buzzer is mounted in the keyboard.
13.2 "EE" ALARM
The dIXEL instruments are provided with an internal check for the data integrity. The "EE" alarm 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", "P3" and "P4"; they automatically stop 10 sec after the probe restarts normal operation. Check connections before replacing the probe.
Temperature alarms "HA", "LA" "HA2" and "LA2" automatically stop as soon as the temperature returns to normal values.
Alarms "EA" and "CA" (with i1F=bAL) recover as soon as the digital input is disabled.
Alarm "CA" (with i1F=PAL) recovers only by switching off and on the instrument.
14 INSTALLATION AND MOUNTING
T620 keyboard shall be mounted on vertical panel, in a 150x31 mm hole, and fixed using two screws
VX620 keyboard shall be mounted on vertical panel, in standard low voltage J-Box, and fixed using two screws
CX620 keyboard shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the special bracket supplied.
The controller XW60K can be mounted in a din rail or wall mounted. It must be connected to the keyboard by means of a two-wire cable ( 1mm). The ambient temperature range should be -10 to 60°C/14 – 140F (Avoid
places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. An enclosure is recommended for certain environments.
