Relays
If the relay outputs are used, the wiring is done at the left-hand side
terminals on the motherboard (see Figure 6). When the relay trigger
point is exceeded, the relay switches on (default). This function can be
inversed by disconnecting the corresponding relay jumper (L1 or L2).
The relay trigger points have been set at factory as defined in the order
form. The points can also be changed with an optional serial COM
adapter 19040GM. For more detailed information see page 12.
