1.2.3 PERMISSIVE (DIN) Input
The PERMISSIVE input is used to
shutdown the system if it is acve.
Connect the input to a PLC or some
other external switch. By default,
the input is acve when the circuit is
open but this can be changed in the
IO sengs. It is internally pulled up to
5 VDC. If it is not used it needs to be
jumpered (Image 1.2.3).
1.2.4 Proof of Closure Input
The PROOF OF CLOSURE input is used
to check that a valve is closed before
the system aempts to ignite.
Important! Failure of this test will
transion the system to the POC
FAILURE state.
Connect the input to a valve’s status
output, pressure switch, or other
device intended to prove the state of
the valve. By default, it is acve when
the circuit is open but this can be
changed in the IO sengs. The input
is internally pulled up to 5 VDC. If this
input is not being used it needs to be
jumpered (Image 1.2.4).
1.2.5 Pressure Switches PS1
& PS2
The Pressure Switch inputs, PS1
& PS2, are generic digital inputs.
They can be used as sources for the
Shutdowns.
By default, they are acve when the
circuit is open but this can be changed
in the IO sengs. They are internally
pulled up to 5 VDC (Image 1.2.5).
