[. . . ] PowerLink REMOTE AC POWER SEQUENCE CONTROLLER AC POWER SEQUENCING POWERLINK REMOTE AC POWER SEQUENCE CONTROLLER QUICK START The illustrations below show several of the most common hookup methods for the PowerLink. There are many other methods and features, however, so please refer to the rest of this manual for more details if necessary. For single unit operation with turn on from local or one remote location. Default is maintained contact closure. +12V START FORCE STATUS REM ON FORCE REM OFF COM GND COM A B C D E F ON LATCHING (MAINTAINED) REMOTE SWITCH OFF Multiple remote switches require use of Momentary Mode. [. . . ] This setting will be useful to interface to other brands of controller that have positive control logic (i. e. they put out a signal to indicate that attached gear should turn on). Maintained switches are generally most convenient when there is only one remote location. When more than one location is required, momentary switches offer the advantage that either the turn-on or the turn-off sequence may be started from any location. The PowerLink is shipped factory-set for maintained operation. It may be easily converted to momentary operation by moving a jumper plug on the PowerLink's circuit board. To do this, first 6 POWERLINK REMOTE AC POWER SEQUENCE CONTROLLER disconnect the unit from AC power. Remove the four screws that secure the top cover. There are three small two-pin connectors near the center of the largest circuit board. A small black suitcase jumper can be moved to set the mode. (Please see Table 4 on this page for jumper numbers and function description. ) to the +12V terminal will start the PowerLink's on/off sequence. The +12V output on the rear barrier strip can be used to trigger the REM input. As in Momentary mode, the REM COM must be connected to the adjacent GND terminal. This mode also requires only two wires in the simplest case, +12V and REM. You may wire any number of momentary switches in parallel. In this mode the START ON/OFF SEQUENCE button can also be used to trigger an up/down sequence. JMP1 JMP2 JMP3 Momentary Mode Maintained Mode, Normally ON (Factory Default) Maintained Mode, Normally OFF NOTE: Connect only ONE jumper of the JMP1-JMP-3 group at a time J1, 2, 5, 6, 9, 10 Normally Open connection for low level relays A, D, B, E, C, F (factory default) Normally Closed connection for low level relays A, D, B, E, C, F MAINTAINED MODE/NORMALLY ON A simple connection of the REM IN terminal to the +12V terminal initiates an OFF sequence. Disconnecting it initiates an on sequence. If the cable run is long, it is recommended that the REM IN wire be tied to the PowerLink's GND terminal during on operation rather than leaving it floating. This will require the use of a third conductor and a double-throw switch. NOTE: The REM COM is floating with respect to the ground of the +12V source. To use the +12V with the REM input, the REM COM terminal must be connected to the adjacent ground terminal on the rear barrier block. In Maintained Mode, do not use the START ON/OFF SEQUENCE button on the front panel.
