Console DTU (Data Transfer Unit)
Installation Instructions
Overview
The TS-DTU will be installed in the dispenser when it is
used as a Remote DTU or inside the building when used
as a Console DTU. These installation instructions are to be
used for installing the TS-DTU inside the building.
When used as a Console DTU, data is received from the
Remote DTU units via power line communication. The data
is then sent to the System Console (TS-550 / 5000 / EMS)
for processing. Unlike the Remote DTU units, the Console
DTU will have no Intrinsically safe sensors connected to it.
Site Inspection
A licensed electrician should perform a site inspection
before installing any equipment. The Console DTU must
be connected to all electrical phases that supply power to
dispensers containing Remote DTUs.
Check for any electrical isolation. Isolation between the
electrical panel and the dispenser can result in poor or
no communication with the DTU. Make sure there is
not a power conditioner between the Console DTU and
dispenser power.
Installation Procedure
Tools and Supplies Needed
• 1/2 " Cord grip / strain
relief
• Multimeter • Mounting screws
• 2 - wire shielded cable • 14 AWG wire (
• Small slotted
screwdriver
one for
each phase and ground)
Step 3 – Power Connection
The Console DTU may use the same circuit breaker as
the System Console but DO NOT connect the power for
the Console DTU inside the Console enclosure. Install
a junction box or wire the Console directly to the circuit
breaker panel.
Ideally, the circuit selected for the console power will be
on the same phase as all dispensers and no further power
connections will be required. If any dispensers are on a
different phase, run wires from the L2 and L3 connections
on the Console DTU to the appropriate circuit breakers
for the required extra phases. If there is any question
about what phase some of the dispensers are on, it is
recommended to connect all three phases to the
Console DTU.
Connect the neutral for the Console DTU to the same
neutral supplying the dispensers. If there is not a clean
neutral return for the DTU then poor quality may result.
Warning: Cycling power to the Console DTU without
powering off the System Console will cause the System
Console to reboot.
Installer must use conduit for connecting the DTU on the
power connection side.
Ground
Step 1 – Remove System Power
Remove power from the TS-5XXX Series System Console
and do NOT return power to the System Console or to the
Console DTU until instructed to do so.
Step 2 – Mounting the Console DTU
Mount the Console DTU as close to the circuit breaker
panel that is suppling the dispenser(s). Remove the cover
and insert a screw (not supplied) into each of the four
corners of the enclosure. Mount the unit to the wall. You
may optionally use the supplied mounting brackets.
Electrical Hazard! Always disconnect power
supplies before installing or servicing the
console TS-DTU. Use proper lock-out and
tag-out procedures to ensure no power is
accidentally applied to the system. Failure to
do so could result in severe injury or death.

Step 4 – Bus Termination Jumper Removal
The Console DTU will provide system bus termination
when installed and running. Therefore the system bus
termination currently provided by the Power Supply
Module needs to be removed. Refer to the TS-5XXX
Series Installation Guide for instructions on how to remove
a module.
Be extremely careful when removing the power supply
module so it does not rub against any other part of the
system. After it is removed from the system, locate the
system bus termination jumper JP1 and remove it (Figure 2).

Re-Install the power supply module, securing it properly in
place and replace the communication bracket as required.
Step 5 – Data Connection
The Console DTU acts as an external System Console
module and therefore must be connected to the system
bus. This is made possible via the external BUS EXT
connection, located on the power supply module.
The bus connection requires 2-wire shielded cable and
FFS recommends Belden 87761. On the Console DTU,
the cable enters through the Intrinsically Safe (I.S.)
opening but is connected outside of the I.S. area, which is
not used in the Console DTU. Therefore the I.S. shield will
need to be removed and discarded. Secure the bus cable
on the Console DTU side using a cord grip.
On the System Console communications bracket, locate
the BUS EXT connector (Figure 4). The connector is
removable for convenient wiring. Refer to the following
table and make the proper BUS (HIGH, LOW, GND)
connections (Figure 3). To make the necessary
connections between the System Console and the DTU,
plug the BUS EXT connector back into the System
Console. Secure the bus cable so it is not accidentally
disconnected.

Step 6 – Review All Connections
Review power and data connections and make sure the
cable is attached securely. Finally replace the Console
DTU Cover.
Step 7 – Power Up
Return power to the System Console and the newly
installed Console DTU.
