IMPORTANT WIRING INSTRUCTIONS FOR PM6C
Output control mode: PM6C can be used as a fault dry contact output or as an electric switch control output, but the same PM6C can only use the same mode, and the two modes cannot be mixed.
Electric switch control wiring: Each electric switch requires 2 control points: closing/opening. When the PM6C is set to the electric control mode, the odd serial number is fixed as the closing control point, and the even serial number is fixed as the opening control point. That is, the relay output 1/3/5... is closing control, and the relay output 2/4/6... is opening control; 1/2 of the relay output forms an electrically operated switch control, and so on.
PM6C Construction and Installation:
The installation size and fixed opening size are consistent with PM6A.
Installation dimensions: 224.3 mm × 110.3 mm, height 35.6 mm
Fixed opening size: 213.5 mm × 82 mm, fixed with M3 screws.
PM6C unit setup instructions:
DIP setting sampling binary mode; Dial "ON" is 0, dial "OFF" is 1
Serial number | Dial code 1 | Dial code 2 | Dial code 3 | Dial code 4 | Address |
1 | ON | ON | ON | ON | 1# |
2 | ON | ON | ON | OFF | 2# |
… | |||||
16 | OFF | OFF | OFF | OFF | 16# |
Dial code 6. InsSel: ON is dry contact mode; OFF is the electric operation mode.
