further directions.
Low-Voltage Control signal and Single-Latching Contact
It is required that the lift is installed and the show position has been set. After setting
show position, jumpers must be added to the connector as shown below.
Low voltage (5 vdc < V < 24 vdc) control signal:
Jumper from N4 Pin 1 to Pin 4, and N4 Pin 2 to Pin 4.
Trigger Voltage to pin 5.
Trigger Voltage ground to N4, pin 4.
(applied voltage sends lift up, no voltage sends lift down)
Single latching contact:
Jumper from N4 Pin 1 to Pin 4, and N4 pin 2 to pin 4.
Contacts between N4 Pin 5 and Pin 6.
(contact closed sends lift up, contact open sends lift down)
