3.6 External Signal Control of the Pressure Controller MP1-200
3.6.1 External Control Input (Terminal Block No.1 to No.8)
The terminal blocks No.1 to 8 are terminal blocks for external control input.
To carry out terminal input, provide an external contact as needed. Use a rated contact that can be
operable at 200 VAC / 6 mA.
a) Emergency stop input (Terminal block No.2 and No.3 input)
If emergency stop input is implemented, the “EMERGENCY STOP” LED on the control panel
turns on and all the boilers in successful communication stop operation, regardless of their
pressure or operation mode (manual/automatic). The contact of the alarm output (terminal block
No.14) also closes.
The input logic can be changed with the internal “SWITCH 1”.
P.16
b) Alarm confirmation input (Terminal block No.4 and No.5 input)
This control signal input has no impact on the MI control
(*)
function. When the Pressure Controller
MP1-200 provides an alarm output (terminal block No.14) due to abnormality in the boiler, this
input stops the alarm output.
7-8: All stop
6-7: All combustion
4-5: Alarm check
