Circuit Board Terminals
2.1
LINE VOLTAGE
A 110-120VAC electrical supply should be externally
fused at 3A and connected to the terminals marked
[LINE VOLTAGE LNE].
2.2
VALVE OUT
The 110-120VAC gas solenoid valve should be
powered using the terminals on the Merlin 1000S+
detailed [VALVE OUT LNE].
2.3
ELECTRIC CONTACTOR
An electrical output can be supplied to an electrical contractor. This should be fused at 3A and
connected to the terminals marked [ELECTRIC CONTACTOR LNE].
This is a relay that changes state in alarm or when the gas is on/off and can be used in
conjunction with the 12vDC output and other external relays that affect other devices and
controls such as purge fans and audible alarms etc.
2.5
PRESSURE SENSOR
This terminal is connected to the gas pressure transducer as shown which
is then screwed into the downstream port on the gas solenoid valve.
Min Operating Pressure = 0.17psi
Max Operating Pressure = 1.45psi
ENSURE THIS IS SCREWED TO THE DOWNSTREAM PORT OF THE GAS SOLENOID VALVE.

2.4
BMS OUT
Terminal connections are available on the circuit board for Building
Management systems etc.
Detailed on the circuit board as [BMS OUT - N/C, COM and N/O]
(Normally Closed / Common / Normally Open).
These are volt free connections.
