ONTROL
The HPTB provides ELCO style connectors (J1-J4) for connection directly to Triconex I/O modules. No
adapter or accessory hardware is required. As with field connections it is strongly recommended to use
shielded cables should the line length be greater than 30m.

HART C
OMMUNICATOR
In HART communications, there is one slave (field device) and up to two masters (e.g. Multiplexer, HART
Communicator, I/O module). The HART Communicator can be connected to the field side terminals as a
secondary master. In the software settings, the MUX 2700 must be the primary master in order to use the
HART Communicator.
There cannot be more than two masters. If three or more masters are connected, a primary/ secondary
conflict will occur and communications will cease with all devices on that loop. When the MUX 2700 is used
with a HART compatible I/O system, the MUX 2700 must be configured as the secondary master.
Otherwise, configure the MUX 2700 as the primary master. The HHT is a secondary master by default, and
can be connected to the loop when no other device on that loop is configured as a secondary master.
Do not connect the HART Communicator to any Intrinsically Safe field wiring unless the
communicator is approved as Intrinsically Safe and is suitable for the actual classification of
the specific hazardous location. Also consider the HART Communicator safety parameters
and equivalent capacitance and inductance before concluding that you can safely connect it
to the I. S. side of the circuit

ETTINGS
The User Switches buffer has eight inputs from a low profile DIP switch reachable through the front label.
The functions of the switches are as follows:
•
Switch 7
•
Switch 6
•
Switch 5
•
Switch 4
•
Switch 3
•
Switch 2
•
Switch 1
•
Switch 0
Further information is given on the front and side labels. In particular, the side label gives the correct setting
of every DIP switch combination.
