Page 3: Introduction
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.
Page 4: Mechanical Installation
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.
Page 5: Electrical Installation
Electrical installation 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 2.5mm to be ﬁtted.
Page 6 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.

Page 9 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.

Page 26: Explanation Of Functions
Explanation of functions The PM4 setup and calibration functions are conﬁgured through a push button sequence. The three push buttons located at the rear of the instrument (also at the front on some display options) are used to alter settings. Two basic access modes are available: FUNC mode (simple push button sequence) allows access to commonly set up functions such as alarm setpoints.
Page 27 This mode is chosen by selecting FREQ at the OPER function. The ratemeter mode can operate in one of 4 basic ways to give diﬀerent display options namely: 1. Rate display, high frequency If HIF is selected at the FREQ RNGE function the instrument acts as a general purpose fre- quency/ratemeter/tachometer.
Page 28 Easy alarm relay adjustment access facility The display has an easy alarm access facility which allows access to the alarm setpoints simply by pressing the F button at the front or rear of the instrument. The ﬁrst setpoint will then appear and changes to this setpoint may be made to this setpoint via the ^ or v buttons.
Page 29 2.0 with a A1PS value of 50 then the relay will remain energised for 2.0 seconds every time the display passes a multiple of 50. Note: If the pass time exceeds the time taken to reach consecutive pass values then the instrument will “store” any relay operations it does not have time to activate and will perform these activations when the total display update rate allows.
Page 30 value. To set a high alarm value go to the A Hi function and use the ^ or v push buttons to set the value required then press F to accept this value. The high alarm setpoint may be disabled by pressing the ^ and v push buttons simultaneously.
Page 31 Alarm relay trip time A tt Display: 0 to 9999 Range: Default Value: 0 Displays and sets the alarm trip time in seconds. The trip time is common for both alarm high and low setpoint values. The trip time provides a time delay before the alarm relay will activate when an alarm condition is present.
Page 32 Alarm relay setpoint or trailing operation A SP or A t1 etc. Display: A SP or A t1 etc. Range: Default Value: A SP Relay operation independent setpoint or trailing setpoint, this function only be seen where more than one relay is ﬁtted. Each alarm relay, except relay 1, may be programmed to operate with an independent setpoint value or may be linked to operate at a ﬁxed diﬀerence to another relay setpoint, known as trailing operation.
Page 33 Example: With duLL set to 4 and brGt set to 15 and the R.INP function set to duLL the display brightness will change from the 15 level to 4 when a switch connected to the remote input terminals is activated. 7.12 Preset value P.SEt...

Refer to the separate “PM4 Panel Meter Optional Output Addendum” booklet supplied when this option is ﬁtted. Determines the high scaling point for the b.SCL mode and has no eﬀect on other modes.

Page 38 7.27 Analog output PI control rec ctrI Display: on or OFF Range: Default Value: OFF Analog output mode - seen only when analog output option is ﬁtted. This function allows selection of on or OFF for PI control analog output. If set to OFF the analog output operates as a retransmission output and uses the functions described in this chapter.
Page 39 work together as follows: RAtE SCLE Input frequency (Hz) Display = RAtE INPt Note: if either the rate input or rate scale factor are set to 0 the scaling will be 1:1 i.e. a 1Hz input will give a display of 1 i.e. it is assumed that there are no scaling factors. Example: If an encoder sensing revolutions of a shaft puts out 20 pulses per revolution a RAtE INPt of 20 and a RAtE SCLE of 60 will give a display in RPM.
Page 40 7.34 Total display decimal point selection tOtI dCPt Display: 0 to number of display digits minus 1 Range: Default Value: 0 Total decimal point selection - Displays and sets the decimal point position for the total display. For example selecting 0 will mean no decimal points (e.g. a display such as 25), 0.1 means 1 decimal point place (e.g.
Page 41 display will round up to the nearest total value. When set to on the display will not round up. For example with totL INPt set to 10 and totL SCLE set to 1 (i.e. 10 pulses for 1 count) and with the display just reset to zero if truncation is OFF then after 6 input pulses the display will round up to show 1.
Page 42 These modes allow a choice of how the grand total will be displayed. The total may be switched between up and down count via the “SET” input and the SINP function. Ensure that the “SET” link is in before attempting to use this input to change count direction. The following table illustrates each mode of operation.
Page 43 7.41 Input edge INPt EdGE Display: RISE or FALL Range: Default Value: RISE Displays and sets the pulse input edge on which triggering will occur. If set to RISE then the rising edge of the input pulse will trigger the input. If set to FALL then the falling edge of the input pulse will trigger the input.

The instrument is required to display in RPM with 1 decimal point place. In this example 20 pulses per second would equal 1 revolution/sec which equals 60 RPM.
