[. . . ] Timer will close door (after a preset, adjustable interval) when the door is opened from certain or all devices, but will leave door open when the door is opened by any other means. These devices are designated by the terminal points to which they are connected. Any device wired to activate the timer (as described above) will also reset the timer to the preset interval if it is energized during the timing period. [. . . ] Mount the 4 position TERMINAL BLOCK on the back wall above the 10 position terminal block, use the holes that are 1" from the top lip of the box. Use (2) #10-32 x 5/8" long self tapping screws to secure in place. Refer to electrical box layout below for location of components in the box.

WIRING CONNECTIONS Refer to the illustrations and instructions describe below to wire new components. NOTE: If a residential radio is wired to the operator to open and close door, the receiver must be re-wired to open only (see diagram below). Determine which limit switch is the open auxiliary switch and remove all three wires (yellow, orange and purple) from the switch and the terminals they are attached to, discard wires. From the new R1 relay remove the red wire (that goes from coil of the relay to the R3 terminal on 3 position radio block) from the coil of the relay and install on common of the auxiliary open limit switch. From the new R1 relay install a new 24" red wire from the coil to the normally closed on the auxiliary open limit switch. From the new R1 relay remove red wire from coil that goes to terminal #1 and discard wire. From the new R1 relay connect new 12" red wire from coil to terminal #11. Install the 12" grey wire to the normally open on the new R1 relay that corresponds to the orange wire in step (i) and connect to terminal #11. Install the 3" brown jumper wire between terminals #11 and #12 (if timer defeat switch is going to be used put switch in place of brown jumper wire). Install the 13" blue wire from the #3 on the timer to the orange wire nut. Install the 13" yellow wire from #5 on the timer to terminal #12. Locate MOV (Metal Oxide Varsitor #76-29V30500) this looks like two orange wires with black heat shrink tubing and install from A1 to A2 on the open contactor coil (see figure on pg. For "T1" type wiring install the 14" brown jumper between terminals #1 an #11. Refer to control wiring features on back page to determine desired wiring type. If open and a start timer is not desired move the yellow wire from terminal #7 to terminal #1. [. . . ] Audible/visible Warning device may be light, strobe, horn, buzzer, or other simular device.
