[j] % L.E.L. TO % v/v CONVERSION
─────────────────────────────────────────────────
Please refer to the remote sensor User Manual.
─────────────────────────────────────────────────
[k] CONTAMINANTS
─────────────────────────────────────────────────
Not applicable to the Control unit. For remote sensor please refer
to the remote sensor User Manual.
─────────────────────────────────────────────────
[l] SAMPLING LINES
─────────────────────────────────────────────────
Not applicable.

[m] ALARM AND FAULT SIGNALS
─────────────────────────────────────────────────
Refer to sections [b] (Operation), [e] (Installer parameters settings),
[w] (Front panel).
─────────────────────────────────────────────────
[n] EXTERNAL POWER
─────────────────────────────────────────────────
The unit is powered at 12Vdc with an external power supply at
12Vdc.
If it is required a system which can operate even when the main
power supply goes off, it is necessary to provide an emergency
power supply at 12Vdc.
─────────────────────────────────────────────────
[o] SPARE PARTS
─────────────────────────────────────────────────
This control unit has no user serviceable parts.
─────────────────────────────────────────────────
[p] ACCESSORIES
─────────────────────────────────────────────────
ACAL10: External power supply 100..264V~ 50/60Hz / 13,8Vdc.
────────────────────────────────────────────────
[q] PERIODICAL CHECK
─────────────────────────────────────────────────
The periodical check should feature the following controls:
a.
(every 3 .. 6 months):
Functional check
of the correct operation
of the entire detection system by applying calibrated gas to each
remote sensor and check of the displayed value.
Refer also to the sensor User Manual for further information.
b.
(every 12 months):
Instrumental check
of the transfer function
of the control unit and correct detection of the abnormal
situations.
This can be done by disconnecting the sensors from inputs and
forcing through a proper calibrator the input current of each
zone to the significant current values (e.g. 0mA: loop broken,
2mA: fault, 4..20mA: normal operation, >20mA: overrange).
─────────────────────────────────────────────────
[r] SPECIAL INFORMATION
─────────────────────────────────────────────────
No additional information or instructions are required other than
those already provided.

[s] TROUBLESHOOTING
─────────────────────────────────────────────────
Problem.
The password has been lost.
Remedy:
Reset the unit with the installer parameter 'Restore default'; In
this case, all settings will be reset to factory values and you will
need to reprogram the control unit.
Problema.
One channel (zone) shows the '
Loop
' fault message.
Possible cause:
The input current loop is broken or the transmitter is not powered
Remedy:
Check connections between the transmitter and the control unit
searching for interruptions.
Check also with a multimeter for the presence of a voltage
around 12Vdc between terminals '+V' and 'Gnd' of the relevant
zone.
