  • Page 3: Introduction

    Introduction General description This manual contains information for the installation and operation of the RM4-FX Monitor. The instrument operates as a frequency/ratemeter/tachometer and will accept pulse inputs from a wide range of input types. The instrument can be scaled to read in any process units e.g. R.P.M., Litres/min etc.
  • Page 4 Standard outputs Two standard inbuilt relays provides an alarm/control function A non isolated transmitter supply selectable as 5V or 24VDC approx. (25mA max.) unreg- ulated is provided. Output options 1 or 2 extra relays Isolated 12 bit analog retransmission (single or dual analog output versions available) config- urable for 4–20mA., 0–1V or 0–10V.
  • Page 5 Entering FUNC Mode Entering CAL Mode 1. Remove power from the instrument. Hold in the button and reapply power. The display will indicate No special power up procedure as part of the is required to enter FUNC mode. "wake up messages" when message is seen you can release the button.

  • Page 6: Mechanical Installation

    Mechanical installation The instrument is designed for DIN rail mounting. The instrument clips on to 35mm DIN standard rails (EN50022). Cut the DIN rail to length and install where required. To install the instrument simply clip onto the rail as shown below. To remove the instrument lever the lower arm downwards using a broad bladed screwdriver to pull the clip away from the DIN rail.

  • Page 7: Electrical Installation

    Electrical installation Electrical installation The RM4 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 for power supply and relays 1 and 2 and 1.5mm for signal input connections and optional outputs.
  • Page 8 Instrument data label example Sensor power supply The standard internal sensor supply may be link selected to provide a regulated 5V or unregulated 24V to power the sensor. The maximum current available is 25mA. The 24V unregulated supplies are only available on the AC powered versions of this panel meter. Note that no more than one link should be fitted i.e.

  • Page 18: Explanation Of Functions

    Explanation of functions 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 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 19 3. Period display, low frequency. With Lo F selected at the FREQ RNGE function the user has the option of either displaying the rate (RAtE) or period (PERd) of the input (chosen via the dISP function). If PERd is selected then the display will show the period (or scaled period if required) of the input pulse rather than the rate.
  • Page 20 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. For this reason the relay may be seen to activate repeatedly for a period after the total update rate has slowed down or stopped.
  • Page 21 by pressing the ^ and v push buttons simultaneously. When the alarm is disabled the display will indicate OFF. If the relay is allocated both a low and high setpoint then the relay will activate when the value displayed moves outside the band set by the low and high setpoints. The value at which the relay will reset is controlled by the A HY function.
  • Page 22 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 23 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 24 (automatic display blanking or dulling) will also cause the duLL function to appear if the d.oFF SECS function is enabled i.e. set to any value other than 0. 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.
  • Page 25 output high value go to the REC~ function and use the ^ or v push buttons to set the required value then press F to accept this selection. Example: If it is required to retransmit 20mA when the display indicates 50 then select 50 in this function using the ^ or v button.
  • Page 26 higher the filter setting the longer the display may take to reach its final value when the input is changed, similarly the relay operation and any output options will be slowed down when the filter setting is increased. To set the digital filter value go to the FLtr function and use the ^ or v push buttons to set the required value then press F to accept this selection.
  • Page 27 5.22 Period display decimal point selection PErd dCPt Display: 0, 0.00.02 etc. Range: Default Value: 0 Period decimal point selection - only seen when dISP function is set to PERd. Displays and sets the decimal point for the period display. Note that the decimal point display is tied to the display range (dISP RNGE) function e.g.
  • Page 28 Note that the period display (in both or FREQ modes) will only be accessible when the frequency range is set to Lo F and hence the input frequency must not be above 1kHz. Select AUgE for an averaged display. The averaged display allows the input rate to be averaged over a period of seconds set by the AUGE SECS function.
  • Page 29 5.28 Display rate or period dISP Display: RAtE or PERd Range: Default Value: RAtE Period or rate display - This function is only seen when the FREQ RNGE function is set to LoF. When using the LoF range the user has the option of displaying either the rate of the input or the period of the input.
  • Page 30 5.30 Rate display time out tout SECS Display: 1 or 9999 Range: Default Value: 1 Only seen if Lo F is selected under the FREQ RNGE function. Displays and sets the time out in seconds when using the low frequency (Lo F) range. The timeout allows very low frequency inputs to be used without the display reverting to zero between samples.
  • Page 31 HiLo - toggle between Hi and Lo displays. This function allows the remote input to be used to toggle between peak and valley memory displays. The first operation of the remote input will cause the peak memory value to be displayed, the next operation will give a valley memory display.
  • Page 32 A1-3 - Allows setpoint access to alarms 1, 2 and 3 etc. up to the maximum number of relays fitted. The remote input function (R.INP) must be set to SP.AC for this function to operate. Note: Only the setpoints which have been given a value will be accessible e.g. if A1Hi is set to OFF then there will be no access to the A1Hi function when SPAC is used.
  • Page 33 5.39 Instrument address for optional serial communications Addr Display: 0 to 31 Range: Default Value: 0 Set unit address for polled (POLL) or M.buS mode (0 to 31)) - seen only with serial output option. Refer to the separate “RM4 Din Rail Meter Optional Output Addendum” booklet supplied when optional outputs are fitted.
