If all of the available access holes and/or wiring terminals in a PS1201 or
sensor's power supply have been used, preventing the connection of other
new devices into the AquaTrend Interface network system, it may be possible
to use an existing device (AquaTrend Interface or Signal Output Module) to
provide network and/or power connections for a new device.
Before connecting a new device to an existing device instead of directly to a
PS1201 consider the following questions:
1. Is the total power consumed by the existing devices, plus the new device,
within the capabilities of a single PS1201? (Refer to the PS1201 manual
for instructions on calculating this.) Failure to confirm this could result in
failure of the existing PS1201 due to thermal overload. Such failure is
NOT covered by warranty.
2. Is there an unused knockout on the existing device, so that the new
connections can be made while preserving network integrity?
The new device can be connected to an existing device using its existing
PS1201. To connect both power and network signals to the new device via an
existing device, proceed as follows:
1. Procure the required length of 4-conductor, shielded cable
(Cat. No. 52158) to make both the power and network connections.
2. Route the cable in accordance with local building codes. Remove AC
input power from the PS1201 that supplies power to all of the devices
involved.
3. Strip approximately six inches of insulation from the 4-conductor cable.
4. Insulate the shield using Cat. No. 40825-00 heat-shrink tubing.
5. Remove about ½ inch of insulation from each of the remaining wires.
6. Remove, one at a time, each wire from the terminal block of the existing
device. Match that wire with the same color wire from the new device.
7. Twist the ends of the two wires together and insert them both into the
terminal block position where the original wire originated.
8. Connect the other end of the new cable to the new device, following the
instructions in the manual supplied with that device.
9. After all connections have been verified, reapply input AC power to the
PS1201, and follow the instructions in the new device's manual for
configuring the new device to function on the network.
Connect only the cable which sends network signals from the existing device
to the new device. Connect the new device power connections to an additional
PS1201 or sensor power supply. Follow the instructions in the PS1201 or
sensor manual.
