1 Introduction
This manual contains information for the installation and operation of the PM4-TR Monitor. The
instrument may be set to operate as a ratemeter or totaliser or allow toggling between rate and
total displays. The SEt OPER function (see section 7.66) allows selection of one of these three
modes. The three modes of operation are:
•totL - totaliser/counter display. The input pulses are totalised, scaled in engineering units
and displayed e.g. Total litres, mm etc. Count up or count down is possible. A total and
grand total may be viewed and reset separately. The grand total is a separate total memory
which allows storage of all the previous totals, alternatively the grand total can be used to
store the number of batches. Explanation and examples of the totaliser functions are given
in the “Totaliser Explanation of Functions” chapter. The totaliser is scaled via the totL
INPt (see section 7.35) and totL SCLE (see section 7.36) functions.
•FREQ - frequency/rate display. The frequency or rate of the input may be scaled in engi-
neering units and displayed e.g. R.P.M, Bottles/min., Litres/hour etc.. For low frequency
inputs (input always below 1kHz) there is an option of displaying either rate or period. Ex-
planation and examples of the ratemeter functions are given in the “Ratemeter Explanation
of Functions” chapter. The ratemeter is scaled via the RAtE INPt (see section 7.29) and
RAtE SCLE (see section 7.30) functions.
•both - total/rate display (display may be toggled to either total or rate). This mode is
primarily used when the display is required to toggle between a rate and total display via
an external contact closure or via the front panel ^and vbuttons (only fitted on certain
display options). For low frequency inputs (input always below 1kHz) there is an option of
toggling between rate/total or rate/period. A total and grand total may be viewed and reset
separately. Explanation of the totaliser functions and setup examples are given in the “Both
Mode Explanation of Functions” chapter.
Selection of operating mode, calibration and scaling are all accomplished by push button operation
(see page 26 for details). Display prompts are given for each function to assist in setting up
the instrument. Changes to input sensor type or optional outputs may require dismantling the
instrument to alter PCB links.
An inbuilt relay provides an alarm/control function, optional relays (giving up to 7 in total),
optically isolated analog (single or dual channel), serial or digital (BCD or binary) re-transmission
and isolated excitation voltage may also be optionally provided. The single analog output option
can be set for retransmission or PI rate control. The dual analog output option allows output 1 to
be set for PI or retransmission, the second output can be set for retransmission only.
Unless otherwise specified at the time of order, your PM4 has been factory set to a standard
configuration, see the function table for your selected mode for default settings. Full electrical
isolation between power supply, input voltage and re-transmission output is provided by the PM4,
thereby eliminating grounding and common voltage problems. This isolation feature makes the
PM4 ideal for interfacing to computers, PLCs and other data acquisition devices.
The PM4 series of Panel Mount Monitors are designed for high reliability in industrial applications.
The high brightness LED display provides good visibility, even in areas with high ambient light
levels.

2 Mechanical Installation
Choose a mounting position as far away as possible from sources of electrical noise such as motors,
generators, fluorescent lights, high voltage cables/bus bars etc. An IP65 or IP67 access cover which
may be installed on the panel and surrounds is available as an option to be used when mounting the
instrument in damp/dusty positions. A wall mount case is available, as an option, for situations
in which panel mounting is either not available or not appropriate. A portable carry case is also
available, as an option, for panel mount instruments.
Prepare a panel cut out of 45mm x 92mm +1 mm / – 0 mm (see diagram below). Insert the
instrument into the cut out from the front of the panel. From the rear of the instrument fit the
two mounting brackets into the recess provided (see diagram below). Whilst holding the bracket
in place, tighten the securing screws being careful not to over-tighten, as this may damage the
instrument. Hint: use the elastic band provided to hold the mounting bracket in place whilst
tightening securing screws.

3 Electrical installation
3.1 Electrical installation
The PM4 Panel Meter is designed for continuous operation and no power switch is fitted to the
unit. It is recommended that an external switch and fuse be provided to allow the unit to be
removed for servicing.
The plug in, screw type, terminal blocks allow for wires of up to 2.5mm2to be fitted. Connect the
wires to the appropriate terminals as indicated below. Refer to connection details provided in this
chapter to confirm proper selection of voltage, polarity and input type before applying power to
the instrument.
When power is applied the instrument will cycle through a display sequence indicating the software
version and other status information, this indicates that the instrument is functioning. Acknowl-
edgement of correct operation may be obtained by applying an appropriate input to the instrument
and observing the reading. The use of screened cable is recommended for signal inputs.
For connection details of optional outputs refer to the separate ”PM4 Panel Meter Optional Output
Addendum” booklet supplied when options are fitted.

3.2 Transducer power supply
The standard internal power supply may be link selected to provide a regulated 5V or unregulated
9V or 18V to power the sensor. The maximum current available is 25mA. The 9V and 18V
unregulated supplies are only available on the AC powered versions of this panel meter. Note that
no more than one link should be fitted in LK1 to LK4 i.e. either LK1 or LK2 or LK3 or LK4.
3.3 Count up/down operation
The SET input may be used in up count/down count operation of the totaliser. Control of mode
of operation is via the S.INP function and via the state of the SET input (open circuit or short
circuit to ground via link or contact closure). See S.INP function for description and operation
table.
3.4 Relay connections
The PM4 is supplied with one alarm relay as standard with connections on terminals 5 and 6,
extra relays are optionally available. The relay is a single pole, single throw type and is rated at
5A, 240VAC into a resistive load. The relay contact is voltage free and may be programmed for
normally open or normally closed operation. The relay will close when power is removed.
3.5 WS-03102 and Rotapulse wiring and link settings
WS-03102 anemometer and Rotapulse flowmeter are commonly supplied with this model. Wiring
and link settings are as shown below:
WS-03102: Wiring - Anemometer WS REF terminal to PM4-TR GND terminal 8 and WS SIG
terminal to PM4-TR IN terminal 11. Shield to LD-TR GND terminal 8.
Input link settings: Links in are LK8 (DC), LK5 (LOWF), LK12 (FREQ) all other links are out.
Suggested settings:
6 of 58 PM4TRMAN-2.7-0
FREQ RNGE =Lo F,t.out SECS set as required.
For kph scaling RAtE INPt = 30, RAtE SCLE = 82.0
For m/s scaling RAtE INPt = 30, RAtE SCLE = 22.8
Rotapulse: Colour code: Black - signal + (terminal 11), Brown - +18V (terminal 10 on AC powered
models), Blue - ground (terminal 8). Input link settings: Links in are LK1 (18V), LK6 (VCC),
LK8 (DC), LK9 (BIAS), LK10 (HYST) all other links are out.
3.6 Ext In (Remote input) connections
The remote input connections are across terminals 7 and 8. A momentary or latching switch can
be fitted across these terminals to suit the operation selected at the R.INP function.
3.7 Input connection and internal link settings
PM4TRMAN-2.7-0 7 of 58
3.8 Notes
HYST2 link should be in for signals between 1V and 5V amplitude (low level of the input pulse
must be below 0.5V). HYST link should be in for signals greater than 5V amplitude (low level of
the input pulse must be below 2V). If the input pulse amplitude is between 100mV to 1V both
HYST and HYST2 links can be taken out but the input will be at its highest sensitivity and will
be more prone to interference due to electrical noise and it therefore not normally recommended.
A maximum of one hysteresis link should be fitted.
The DC coupling link should be in for frequencies less than 10Hz.
The BIAS link should be in when input signal does not go below 0V.
For inputs above 24V (48VDC or RMS max.) both the VCC and GND link should be out.
The FREQ link should generally be left out. It can used when the display is having difficulty
registering sinewave AC inputs. If at high frequency (above 10kHz) and with input signals above
2VRMS difficulty is found in obtaining a stable display this link can be tried and it may in some
circumstances help to stabilise the display.
The LOW FREQ link is generally used for filtering out contact bounce when relay or switch contacts
are used. It can however be used with other input types to filter out high frequency noise provided
that the maximum input frequency of the pulse signal is less than 80Hz.
