For
Zone 1
applications a transducer certified to
Sira 02ATEX5104X
is
used, and must be supplied via a 4000A breaking fuse, which is fitted as
standard to the
Ultra 5
.
For
Zone 0
a transducer certified to
Sira 02ATEX2103X
is
used, which
must be connected to the
Ultra 5
controller via an external Zener barrier.
See transducer label for certification details.
Single Transducer
mode is used to measure space, level, distance, volume
or flow and the transducer should be
connected
to
Transducer 1
input
terminals.
Dual Transducer
mode is used to measure
Differential
and
Average
. For
Differential
, the
upstream
transducer should be
connected
to
Transducer
1
input terminal and the
downstream
transducer to
Transducer 2
input
terminal. In cases where the
Ultra 5
is required to measure
Average
, then
transducers can be
connected to either
one
.
Relay Outputs
The five relays can be programmed for a variety of alarms, pump control, or
other process functions. The relay contacts are all rated at 5A at 240V AC.
All connections should be such that the short circuit capacity of the circuits
to which they are connected, is limited by fuses rated so that they do not
exceed the relay rating.
Current Output
This is an isolated (floating) mA output (to 150 V), of 4 - 20mA or 0 -
20mA, and the load should not exceed 500
.
Current Input (Optional)
This feature is available as an option only. Please consult Pulsar for further
details. The current input is an isolated (floating) mA input (to 150 V), 4 -
20mA or 0 -20mA.
Temperature Input (Optional)
The external temperature sensor allows more localised compensation of the
measured distance due to changes in temperature.
There are two models, Type A and Type B as follows:
Type A
-25

C to 50
