SVS 12HSE LIFT Installation Instructions Manual - page 11
b. Connecting a Touch Screen Controller (External Controller)
The simplest external controller connections are to use the White wire (pin 1) as the common and the Black (pin
3) for down to Show position and the Red wire (pin 2) for up. For this and other wiring options please refer to
the external controller wiring diagrams in the Appendix. Also:
1. Program a release of relays to stop the Lift on up and down positions
2. Program a time out after the normal runtime, 2 seconds max. (SVS Lifts raise/lower at 1-inch/second.)
3. Program an exclusive lockout on up and down so that both cannot be activated at the same time. (Note:
SVS Lifts have a lockout function that disables the Lift when it receives a up and down command at the
same time. Removing one of the two commands releases the lockout condition.)
4. Hold relays on to raise/lower the Lift.
5. Never leave voltage on the up and down. Always program a release after the travel time has been
achieved.
If you have any questions please contact SVS for proper wiring.
9. ACCESSORY INSTALLATION
Please refer to the accessory installation instructions located in the accessory shipping crates for specific
instructions for each accessory. The Accessory #2 Plenum Shroud requires that hardware be added to the
threaded rods supporting the Lift before the Lift is installed. The Accessory #1 Ceiling Closure and FP1 Closure
Panel attach the ceiling closure support brackets on the platform of the Lift using supplied threaded rods.
