About the Zenith 140
The Zenith 140 is a state-of-the-art pump, and level controller, that provides
advanced operating routines suitable for an extremely wide variety of
applications. The system combines premium specification with high
performance even in the most arduous applications where high turbulence
and foam or froth is present.
Functional Description
The Zenith 140 level and pump controller is a highly developed ultrasonic
level measurement system which provides non-contacting sophisticated
pump and level control routines suitable for an extremely wide variety of
applications.
Easy calibration and maintenance free “fit and forget” performance mean
that you can install the Zenith 140 pump controller rapidly and with
confidence. Six user-definable relays with adjustable, individual on and off
points, seven user-definable digital inputs, isolated mA output, RS 232 and
intelligent performance logging software features provide the user with a
superior pump management system and comprehensive level measurement
information.
The Zenith 140 operates on the principle of timing the echo received from a
measured pulse of sound transmitted in air and utilises the unique DATEM
software (Digital Adaptive Tracking of Echo Movement). This is an entirely
new digital mapping technique developed especially for the Pulsar Ultra
range.

It gives the system the edge when identifying the “true target level” in the
face of competing echoes from pipes, pumps or other obstructions. When
coupled with the powerful, long range abilities of a dB transducer and radar
range, the Zenith 140 level and pump controller has no equal.
The Zenith 140 can measure from 0.077m to 25m from the face of the
transducer to the surface being monitored, dependent on the transducer
used.
The Zenith 140 can show level, space, distance, on the display. The relays
can be programmed to activate alarms, pump starters, or other control
equipment. In addition, the digital inputs can be used to modify pump and
control regimes to optimise performance. There is an isolated 4-20 mA
output that can be connected to a chart recorder or PLC, to monitor level,
space or distance, independently from that shown on the display. There is an
RS232 port, so that the Zenith 140 can be operated remotely by a PC or
other equipment.
The Zenith 140 is programmed by the built-in keypad or by PC via the RS
232 Serial Interface (optional). All the parameters are stored in non-volatile
memory, so are retained in the event of power interruption. A second
backup copy of all parameters can also be retained in the Zenith 140, in case
a previous set of parameters needs to be restored.

CHAPTER 2 ZENITH 140 INSTALLATION
Unpacking
Power Supply Requirements
The Zenith 140 can operate from AC supply or from a DC battery. The AC is
either 85-120V 50/60Hz or 170-240V 50/60Hz, depending on the position
of the selector switch. The DC is 18-36V. In all cases the Zenith 140 will
typically consume 6W of power, with a maximum of 10W.
Important Information
All shipping cartons should be opened carefully. When using a box cutter, do not
plunge the blade deeply into the box, as it could potentially cut or scratch
equipment components. Carefully remove equipment from each carton,
checking it against the packing list before discarding any packing material. If
there is any shortage or obvious shipping damage to the equipment, report it
immediately to Pulsar Process Measurement Limited.

ZENITH 140 INSTRUCTION MANUAL
16
Location
The Zenith must be mounted in a non-hazardous (safe) area, and the
transducer fitted in the hazardous area.
When choosing a location to mount the enclosure, bear in mind the
following:
•Ensure that the Zenith 140 is installed in a “Safe”, non-hazardous
area.
•For a clear view of the LCD display, it is recommended that it is
mounted at eye level.
•The mounting surface is to be vibration free.
•The ambient temperature is between -20°C and 50°C.
•There should be no high voltage cables or inverters nearby,
Important Information
All electronic products are susceptible to electrostatic shock, so follow proper
grounding procedures during installation.

When using 2-core screened extension cable, the Black and Green wires of
the transducer should be connected to the screen of the extension cable.
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 Zenith.
For Zone 0 a transducer certified to Sira 02ATEX2103X is used, which must
be connected to the Zenith controller via an external Zener barrier.
See transducer label for certification details.
When using the Zenith 140 in a single transducer mode, to measure space,
level or distance, the transducer should be connected to Transducer 1
input terminals. In applications where it is required to measure Differential,
then the upstream transducer should be connected to Transducer 1 input
terminals and the downstream transducer to Transducer 2 input terminals.
In cases where the Zenith 140 is required to measure Average, transducers
can be connected as required.
