16, 17. Fill and Prove
Gas Fill Time.
The Fill Time should e set such that there is sufficient time to fill an empty pipe work
system to full / normal pressure while ensuring a minimum escape of gas where a leak
exists.
(Factory default setting is 5 seconds).
Gas Prove Time. This should e set such that the smallest leak can e detected. This time
can e set up to a maximum of 9 minutes. Increasing this time effectively makes the
system more sensitive to gas leaks.
(Factory default setting is 1 minute).
FILL switch @ 1,2,3,4,5,6,7,8,9,0 = 1s, 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, 10s,
PROVE switch @ 1,2,3,4,5,6,7,8,9,0 = 1m, 2m, 3m, 4m, 5m, 6m, 7m, 8m, 9m, 30s,
The prove time can e extended using FILL/PROVE MULTIPLIER, see No 18.
18. Fill/Prove multiplier
SW = X2 This dou les the fill & prove time.
SW = X0.5 This halves the fill and prove time test, please note the minimum prove time is 30
seconds which cant e reduced any lower.
Fan commissioning: This is for use during setup & commissioning to temporary disa le the ventilation interlock
this allows a gas engineer to work on the system even if the ventilation system hasn’t een completed.
Lift valve - applies 230volts to power open the gas valve. This allows you to manually pressurise upstream of
the valve.
Pressures - This will display oth the inlet and outlet gas pressure at the gas valve on the LCD screen. This
allows a visual indication of the gas tightness of the installation as well as an indication of the solenoid. The
same action can e preformed y pressing display “ lind utton A”.

15. Option Switches
OPTA: ON = Hi CO2 isolation, OPTA OFF = Low CO2
OPTB: ON = No Gas isolation due to High CO2, OPTB OFF = EM Stop On
(If OPTA & OPTB are oth off then the BMS relay changes to oth EM-Stop and CO2 alerts states.)
Spare : Unused.
Reverse sender: Allows the inlet/outlet signals to e switched (use under guidance from edem)
