5.4 Appendix 4 – Troubleshooting
Symptom Cause/ Solution
The display shows the condition
“ACTUATOR CIRCUIT”
“ NOT READY”
This indicates that the actuator type has not been ‘learnt’ – or that a
wiring fault caused the learn process to be aborted.
The control panel must determine the exact characteristics of the actuator
and wiring connected to the Actuator terminals. This is carried out from
the commissioning menu:- COMMISSIONING->EXTINGUISHING-
>OUTPUT SET_UP. Refer to section 3.3.3.1.
The display shows the condition
“ACTUATOR CIRCUIT”
“SHORT CIRCUIT” or “OPEN CIRCUIT”
1. Wiring fault on the actuator circuit – check wiring.
2. The wiring or actuator used has been changed/ modified. Re-learn the
new actuator characteristics – see section 3.3.3.1.
After commissioning, the control panel
appears to be stuck in Manual Only Mode.
I have no key-switches fitted/ activated.
The factory settings of the control panel mean that the level-2 menu
mode select function defaults to Manual Only Mode – to avoid inadvertant
triggering during installation.
Change the level-2 menu mode from the following menu:-
Level 2 Menu->EXTINGUISHIN MODES->TRIGGER (select
‘AUTO+MANUAL’).
Note that if factory settings are restored, from the commissioniong menu,
the Manual Only Mode will automatically be re-instated.
I can’t reset the control panel during the
pre-discharge countdown.
As default, resetting the gas release during the countdown is prevented
(to comply with EN12094-1). A configuration setting can be changed to
allow reset during this time – see section 3.3.3.1 (IN COUNTDOWN
setting).
When testing the system I have to wait until
the reset allowed time has elapsed.
By entering the engineers code to select the EXTINGUISH MODES
menu from the Level-2 Menu, an option ‘STOP RELEASE’ is presented –
select this option to cancel the current activation sequence (allow a
reset).
The display shows the condition
“VALVE MONITOR INPUT”
“VALVE STUCK”
Note that the Valve monitor Input requires a different End Of Line resistor
value for the ‘normal’ condition. If no valve is being monitored fit two 6.8K
Ohms resistors in parallel across the terminals (or a single 3.3K Oms
resistor).
