6.4 Ganged System
A ganged system consists of two or more SEQs connected together in such a way that they all turn on and off
together. Figure 6 shows how to connect and program each unit in a three-unit system. If only two units are to be
ganged together then ignore the middle unit in the diagram. If more than three units are to be ganged together
then keep the first and last units set up as shown, add units in the middle and set them up and connect them in
the same way as the middle unit in the diagram.
The remote control inputs should be connected to the first unit, and the same control options are available as for
a single-unit system. If confirmation feedback is required for a central controller, use the aux relay contacts on the
last unit.
The delay times should be set the same for all the SEQs unless you want to skew the turn-on or turn-off points
from one unit to the next.
If the low and high voltage shutdown points are narrowed from their defaults of 90V and 150V this should be done
on the first unit only. The other units should be left set to 90V and 150V.The two restore options should only be
enabled (if required) on the first unit. The self-test shutdown should be the same for all units.
If an over-ride is required connect it to the first unit.
