Unpacking
Power Supply Requirements
The Flow Monitor can operate from AC supply or from a DC battery. The
AC is 85 –264V, 50/60Hz. The DC is 22 - 28V. In all cases the Flow
Monitor will typically consume 8W of power, with a maximum of 10W.
Location
All electronic products are susceptible to electrostatic
shock, so follow proper grounding procedures during
installation.
The Flow Monitor must be mounted in a non-hazardous (safe) Area.
When choosing a location to mount the enclosure, bear in mind the
following:
•Easy access to the enclosure is maintained.
•The mounting surface is vibration-free.
•The ambient temperature is between -20ºC and 50ºC.
•There should be no high voltage cables or inverters close by.
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.

Page 6
Dimensions
The dimensions of the mounting holes are as shown below.
The Flow Monitor should be mounted by drilling four holes suitable for size
8 screws (length and type to suit your application) And fix all four screws by
removing the top cover to access the pre-moulded mounting holes which are
located in the base of the enclosure under the lid retaining screws.

Page 7
The full dimensions of the enclosure are as shown below.
Cable Entry
There are 3 x M20 cable glands, suitable for 6 –12mm cables, fitted to the
base of the Flow Monitor enclosure.
Important Information
All cable glands should be tightened to the manufacturer’s specifications.
The terminal compartment cover screws should be tightened to 0.5Nm
Care should be taken not to over tighten the screws.
Care should be taken not to over tighten the screws.

Terminal Connections
Power
The Flow Monitor can be powered from mains AC or from a DC
source/battery and where a backup DC power source is connected it will
automatically take over in the event of AC power failure; DC will
automatically power the unit. When AC returns it will switch back.
FlowPulse Sensor
The FlowPulse sensor should be installed and connected, in accordance with
the FlowPulse manual.
Wire the FlowPulse sensor to the Flow Monitor sensor terminals, as on the
previous page.
Relay Outputs
The two relays can be programmed to a variety of alarm & control
functions. The relay contacts are all rated at 2A at 240V AC. All
connections should be such that the short circuit capacity of the circuit 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 active mA output of 4 - 20mA or 0 - 20mA, with an
option of a passive mA output. The load should not exceed 1K

.
RS485 termination switch
By default, this is switched off, to enable RS485 termination both switches
need to be switched to the ON position.
Important Information
If the equipment is installed or used in a manner not specified in this manual,
then the protection provided by the equipment may be impaired.

Page 10
AC and Fuse Location
AC mains power fuse is located, on bottom board to the left and above of the
power input terminals, as previously illustrated in the Terminal Connections Detail
drawing.
Important Information
Never operate the Flow Monitor with the cover open.
An external switch or circuit breaker should be installed near to the Flow
Monitor to allow the supply to be removed during installation and
maintenance. In addition, the relay contacts should also have a means of
isolating them from the Flow Monitor.
Interconnecting cables must be adequately insulated in accordance with local
regulations. Strip back 30 mm of the outer insulation of the cable. Strip 5 mm
of insulation from the end of each conductor. Twist all exposed strands of the
conductor together. Insert the stripped conductor into the terminal block as far
as it will go and tighten the terminal block screw. Ensure that all strands are
firmly clamped in the terminal block and that there is no excess bare
conductor showing, and no stray strands.
Preparation for Operation
Before switching on, check the following:
✓The Flow Monitor is mounted correctly and is in a ‘safe’ area.
✓The power supply is correctly installed.
✓The relays are connected correctly.
Maintenance
There are no user serviceable parts inside your Flow Monitor, except the
mains power fuse. If you experience any problems with the unit, then please
contact your local Pulsar Process Measurement distributor for advice.
To clean the equipment, wipe with a damp cloth. Do not use any solvents on
the enclosure.

Your Flow Monitor can be programmed directly via the integral keypad.

Operating the Controls
Display
Whilst in the Run Mode it will display the current flow or velocity reading
and its units of measurement, along with the mA output and status messages
with regards to the communication status and Fail Safe Mode.
When in Program mode, the display is used to read information on the menu
system, the parameter number and parameter details and values, which can
be entered.
During Test Mode the display is used to monitor the simulated flow or
velocity and mA output.
1) Main Display, 12-digit alpha numeric display:
Run Mode:current measurement displayed, dependent on measurement
unit's chosen, and value of Hot Key function selected.
Program Mode: displays parameter number and values entered for
parameters.
Test Mode: displays simulated flow or velocity.
2) Auxiliary Display, scrolling 12-digit alpha numeric display
Run Mode: displays units, totaliser or status messages on
communications, detail of Hot Key function selected.
Program Mode: displays Menu and Sub Menu headings, parameter
details and options.

Hot Keys
There are five hot keys on the keypad, which can be used to quickly access
common parameters for viewing only, while in Run Mode. Pressing the hot
key once will display the first parameter, then repeated pressing will display
the others, then the Flow Monitor reverts to Run Mode. In program mode,
they have different functions, the functions are shown below.
