Installation & Operation
3.1
System ON and OFF
Turn the Fans On.
Turn the key switch to ON position.
To turn the system off, turn the key switch to OFF position.
3.2
Emergency Shut Off
The emergency shut off button is located on the front of the panel.
There is also a facility for remote shut off buttons to be wired in series on the circuit board.
The emergency shut off button(s) will cut off the gas supply when activated.
To reinstate the system, the emergency shut off button(s) will need to be reset and the panel
restarted.
3.3
BMS integration
The Merlin 1500S can be integrated with a BMS to make or break a circuit on
gas on/gas off, (valve open or valve closed). This will tell the BMS whether or not
110-120VAC is being sent to the solenoid.
There is a dip-switch located on the inside facia of the Merlin 1500S labelled
[BMS SEL].
This is factory set in the OFF position which signals the BMS on gas on/gas off.
When switched to the ON position, the 1500S will only signal the BMS on a fault, i.e.
fan fault, CO2 high level detected, gas detected, EM Stop pressed, etc.
3.4
Fan Switch Integration
There is the facility to connect a Fan Switch (FS1 or FS2 sold separately).
The Fan Switch provides the facility to turn on the fan(s) when the key switch on the Merlin 1500S
is in the on position and turn the power off to the fan(s) when the key switch on the Merlin 1500S
is in the off position.
There is a dip-switch located inside the facia of the Merlin 1500S labelled [EM SEL].
This is factory set in the OFF position which instructs the system to shut down the fan(s) and gas
supply on activation of the Emergency shut off button(s).
On installation, this can be switched to the ON position if required. This will
instruct the system to leave the fans on and only shut off the gas supply on
activation of the Emergency shut off button(s).
Note: This option is not available if Fan Switch is not installed.
