Wiring the PT5002
Wiring for Use as a High Flow Shutoff Device with a
Stand-alone Controller
Use a Normally Closed Master Valve
Connect one leg
of the master valve
solenoid wire to
terminal 15 on TB3
(or to terminal 18 on
TB4)�
Connect the
controller master
valve wire to terminal
14 on TB3 (or to
terminal 16 on TB4)�
OTE:
N
Wire master valve common to controller common�
Use a Normally Open Master Valve
Connect one leg
of the master valve
solenoid wire to
terminal 13 on TB3
(or to terminal 16 on
TB4)�
Connect the power
supply line wire to
terminal 14 on TB3
(or to terminal 18 on
TB4)�
OTE:
N
Wire master valve common to power supply common�
Flow Sensor Inputs
The PT5002 is designed to accept pulses from open collector transistors or dry
contact closure transmitters�
Before making any connections:
•
Always use shielded wire to protect the signal line from external noise (ground
shield to terminal #3)�
•
Make sure the signal lines are not bundled with or touching power lines�
