Page 3: Introduction
Introduction PM10 is a modular panel-installed meter and controller family for industrial use. PM20A is one type of chassis in this family. It is a 96x96 mm panel meter chassis consisting of an enclosure, motherboards, and a display. Various types of input and output cards can be fitted inside. -
Page 4: Assembling A New Pm20A
Assembling a new PM20A This chapter may be skipped if the device is ordered pre-built. The PM20A internals consist of two motherboards, support structures, the display board and the optional cards: Support plates Slot F Slot J Display board PM20ADISP... - Page 5 Snap the appropriate back plate opening covers off by fingers or by a flat-bladed screwdriver. Slide the motherboard and the cards in the enclosure guiding the cards in the grooves and refit the front panel or the back plate. Page 5 - Assembling a new PM20A...

Page 6: Mounting In A Panel
Mounting in a panel Prepare a panel cut-out per IEC 61554: width and height 92.0…92.8 mm. Place the gasket around the PM20A body. Slide the device in the opening and fasten with two clamps, either on the sides or on top and bottom. -
Page 7: Configuration Menu Overview
Configuration menu overview The configuration menu items of the display are explained in the relevant chapters. This is just a quick overview. The other cards have menus of their own, not covered by this manual. Display Trunk Auto fill Defining the contents of the display. Page 8. -
Page 8: Using The Display
Using the display Indicators Fault indicator Can be used to indicate alarms, digital Indicates that there is input states, and which page is something wrong. currently displayed. Gives a hint what the accompanying reading is. Can be 1-3 letters or Reading digits. -
Page 9: Automatically Configuring The Display Contents
Automatically configuring the display contents In most cases, the task of defining the display (page) contents may be left to PM20A. It will automatically query the input cards and place their readings on the display, beginning from slot A inputs. Since the inputs that are switched off are not included, configure the inputs first according to the input card manuals. - Page 10 Title+4Val The middle and bottom rows have two readings each. Top row has a tag consisting of the first and last channel numbers separated by a dash. Each reading should have up to three digits. 6Val Every row has two readings, maximally utilizing the display. If several pages are used, the indicators above the display can be used to indicate which page is being displayed as there is no room for tags.

Page 14: Configuring The Colors Globally
Making a color to change at an event PM20A can change the display colors to get user attention e.g. when an alarm is triggered. Each reading (and tag) can have two alternative colors in addition to the normal color, e.g. for a warning and an actual alarm, or for lower and upper alarms. -
Page 15: Using A Dimmer
If both Alm1/Src and Alm2/Src are alarming, Alm2 will win. Using a dimmer PM20A allows controlling the display brightness from various sources, typically from an external potentiometer or control voltage, but it is also possible to use a setpoint for this. To use the dimmer: 1. -
Page 16: Configuring The Page Indicators
It is possible to assign up to 5 leftmost indicators to this task. When a single indicator is not enough to express the page number, PM20A will use multiple indicators together. The user obtains the page number by summing the number values next to the indicators. E.g. -
Page 17: Attention Light
3. Corresponding amount of Src settings will be revealed. Set each of them to point to some register, e.g. an alarm on a relay card. To draw attention when there is some fault recognized by PM20A, set one of the Src settings to the AnyFault register (page 21). -
Page 18: Allowing The User To Interact: The Setpoints
The setpoints turn the “output” nature of the display to “input” from the user. The user may use the keys to adjust the setpoint values, affecting the operation of PM20A in various ways. The setpoints in this context are not directly related to alarms or controllers. They are merely something the user may easily adjust. - Page 19 If it is not acceptable that anyone can adjust the setpoints, set a password in Setpoints > Code. The user must enter it before adjusting a setpoint. Once entered, the setpoints are unlocked for 60 seconds. The setpoint is ready for use. Move to the newly configured page on the display. Push * and the following should happen: ...

Page 20: Having Auxiliary
If the user will not touch the keys in one minute, the trunk page will be displayed. The PM20A display has 18 configurable pages. Some of the first pages (e.g. pages 1 to 4) are used in the trunk, but the rest are free to be used as auxiliary pages. -
Page 21: Ambient Light Sensor
Ambient light sensor The front panel includes a coarse non-calibrated ambient light sensor. The result is available in the Amblight register. The reading varies from 0 to 100. The light sensor may be used as a temporary input when testing the PM10 functions. The reading may be affected by covering the sensor with a finger. -

Page 25: Editing A Reference
Editing a reference The references are used to link the different, autonomous blocks of the system together. E.g. for an analog output, the source must be configured, as the output may follow various sources (called registers) from any of the cards. Similarly, the display contents are configured to come from somewhere. -
Page 26: Using The Usb Port
Using the USB port A micro USB port is available at the back of PM20A. It can be used for configuring the device with the Nokeval Mekuwin configuration software. The information below applies to PM20ADISP firmware V1.0. When connected to a computer, PM20A appears as a virtual COM port, accepting Modbus RTU commands. -
Page 27: Functions, Tables, Elo
Functions, tables, Elo… For processing the input signals and to allow tuning the device for many tasks, the display card provides the following configurable operational blocks: Functions take one or more inputs and do some simple operation on them, like subtracting two inputs. -
Page 28: Maintenance
Maintenance The device doesn’t need regular maintenance. The analog input and output cards can be recalibrated, when maximum accuracy is desired. Now and then check that the fault indicator is not on. The enclosure, including the front panel, may be cleaned with a moist cloth. Use mild soap water or isopropyl alcohol. -
