Note:
• Use shielded sensor cable(s). Keep cable as short as possible, but locate it away from noise sources.
• Connect the ±15 VDC sensors at DB–15 female sensor connector exactly as shown in the drawing above.
Do not connect other pins, that may damage power supply or controller!
• Connector: Use only screws with 4-40UNC thread for fastening the connectors!
Pins 4 and 8 must be bridged for operation!
An optional switch would allow for motor interlock to
prevent valve from moving.
