Wire fault supervision: EOL resistors are optional with the
MyDro. When utilized and installed properly (at the far end
of the cable wired parallel to the switch) they allow the
system to alarm on a wire fault. Software selection of
this is done from the touch screen. From the config
screen, go to Digital Input Setup and then Mode.
Choose Digital Input Dry Contact NF for no
EOL resistor (no wire supervision).
7. Wire the output relays. The output relays
are single pole, double throw and rated
up to 30 VDC or 120 VAC at 5 amp
maximum. They are used for remote
control applications such as Tank and
Well, and analog or digital interconnect.
You can wire the relay normally open
(default) or normally closed (refer to
Appendix B).
Warning:
Relay behavior on
communication failure is configurable
under the Config. Menu/Relay Comm
Fail Setup as Deenergize or No
Change.
Warning:
If power to output relays is
supplied by Mission auxiliary power
port it is software configurable as 12
or 24 VDC. Specify coil voltage of
interposing relays appropriately.
