System Overview
Display Panel
Connect the intrinsically safe Display
Panel to terminals 5, 6 and ground in
the intrinsically safe (EExi) junction box.
Analog Outputs
There are two analog outputs which can
be of passive or active type (external or
internal loop supply). The primary
output has a HART interface.
Connect the primary analog output to
terminals
1
and
2
.
Use the EExe junction box for non-
intrinsically safe applications, and the
EExi junction box for intrinsically safe
applications.
Digital Communication
Saab TankRadar Pro can be equipped
with HART interface or Saab TRL/2
Bus interface.
The Saab TRL/2 Bus may only be
connected to the non-intrinsically safe
(EExe) junction box.
Connect the serial data transmission
cables to terminals
1
and
2
.
Power Supply
Saab TankRadar Pro operates on 100-
240 V AC or 24-48 V DC. Check the
label on the transmitter housing that the
correct power supply board is installed.
Connect the power supply to terminals
3 and 4 in the non-intrinsically safe
Junction Box (EEx e).
