PROBE AND SENSOR WIRING PRECAUTIONS
To The Installer! You Must Read And Understand This Information.
Input/Output Wiring Positions and Labeling
In all cases, the devices wired to the console’s input/output terminal blocks must be recorded to prevent
improper replacement during installation or service.
IMPORTANT! During programming, the devices wired to each terminal are identified and stored in system
memory. If a device is removed and reconnected to a different set of console terminals after programming,
the system will not properly recognize the data being received. To ensure trouble-free operation, you
should fill out the Circuit Directory as you connect each device.
CIRCUIT DIRECTORY
The circuit directory is adhered to the inside of the right-hand door. It should be filled out by the installer as the
console’s input/output devices are being connected to the console to record the physical location and type of
device wired to each input or output terminal of the console.
In the example directory shown in Figure 36, Input 1 connects to the Backup Generator. Relay 1 is connected to
an overfill alarm device. Sensor locations 1, 2, and 3 connect to two different sensors on the three tanks. Probe
locations 1 - 3 connect to Mag probes in the three tanks.
Wiring Assignments
Identify all wires according to their terminal block location using the self-adhesive numbering labels furnished.
Accurately record on the circuit directory the location of each device as you attach wires to the terminal block.
WARNING
The equipment is used in location where lethal voltages and explosive vapors
or flammable fuels may be present.
Care must be taken when installing, servicing or replacing parts in the system
or serious injury or death from explosion, fire or shock may occur.
For this system:
1. Comply with the latest National Electric Code, federal, state, and local
codes, and any other applicable safety codes. In addition, take necessary
precautions during installation, service, and repair to prevent personal
injury, property loss and equipment damage.
2. Refer servicing to trained and qualified personnel only.
3. Substitution of components may impair intrinsic safety.
4. Be sure AC power is “OFF” before opening the console panel covers and
connecting probe and sensor wires. Do not short any voltage across
any barrier terminal including sensors or probes.
