SEC-B
Test fail check all appliances:
The system has found an escape of gas, the most common cause is an open appliance. Check all appliances are off and restart
the pressure test. If the system still reports test fail then a leak will be on the pipe work. Using “Blind button A” (see page 2) you
can view the gas pressures at the valve, the outlet pressure must remain at least 90% of the value of the inlet pressure or a leak
will be declared.
Error from valve sender unit
System is not receiving data from the sender unit. The pressure sender is a required part of the system and cannot be “linked
out”. Verify the sender is correctly wired and that you have a green flashing LED on the sender unit.
Detector fault XX
The system believes it has lost connection to a detector on address XX, verify detector addresses and press the “learn
button”
(23)
. Verify all connected detectors are being registered by pressing “blind button B” (see page 2). If you have no
detectors connected to the system pressing the learn button will clear the error message.
Supply and/or Extract fans not running.
The system can monitor the fan status via a current monitor or air pressure switches. These provide a closed contact to
terminals S1 and E1, it is a requirement when using fan interlocking that the fans be running (and therefore the S1 and E1
receiving a closed contact) before the system can begin a gas pressure test. If at any point the fans stop running (opening the S1
or E1 contact) the system will isolate the gas and report fans not running. Check that the fans are not only switched on, but
actually running and moving air.
Low incoming gas pressure.
The system requires a minimum of 13 mBar of pressure at the inlet side of the gas valve, this is to ensure a correct strength
flame. If at any time the incoming pressure drops below 13mBar for more than 10 seconds the system will isolate the gas and
report “low incoming gas pressure”
Note: if this occurs during installation check the sender unit direction of flow, if the sender is installed backwards the system will
believe the “outlet” to be the “inlet” and therefore see an open end as being low incoming gas pressure.
Emergency stop button pressed.
The system has an panel mounted emergency stop and connection inside for remote buttons. First check the panel button (once
pressed some require resetting by twisting and releasing). Clear the message by turning the main system switch off and then
back on, if the message remains check any remote buttons and their connections. The terminal for the remote buttons requires
a volt free normally closed contact, ensure all remote stop buttons, thermal links any another connected systems (BMS/Fire
panels) are reset and the contacts are closed.
In the event of any alert the system will always give a reason on screen as to the cause.
