Power Generation Display Unit
User Manual 801309
1. Introduction
The Power Generation Display Unit is designed to display the power generated by any Power Generation system but is
usually used on a renewable energy generation site, e.g. Photovoltaic (PV) or Wind. For a PV system, PV panels would
typically be installed on a building and provide power directly to the mains grid via inverters. Energy meters provide
pulses to the Power Generation Display Unit to enable the energy generated to be counted and displayed.
The Power Generation Display Unit is available in two sizes as described in the following table:

2. General Arrangement
The unit comprises a back-box which houses the Power Supply PCB, Control PCB and Display PCB Assemblies. The
back-box is covered with two sheets of clear acrylic (420 x 300mm or 600 x 500mm) which are designed to trap a fixed
graphic of the end users choice. The backlit LCD graphics display is visible through an aperture in the graphic. The
sheets of acrylic are held together by the surrounding bezel and M8 fixings.

2.1. NOTE: LCD Display
When fully assembled, the LCD Display sits slightly proud of the metal back-box. For this reason the unit is
supplied in parts which are typically assembled at installation time. The LCD Display should not be fitted to the
four nylon pillars provided until the back-box has been fitted to the supporting wall – see section 3.4

3. Installation
3.1. Disassembly
Carefully remove the four M8 fixings in the four corners of the bezel and remove the bezel.. If this is an existing
installation, remove the tape which is applied to the edge of the two sheets of acrylic (this should be done carefully
to avoid dropping the front sheet of acrylic). Remove the front sheet of acrylic and any graphic that is installed.
Remove the eight M4 countersunk screws that hold the rear sheet of acrylic to the back box.
3.2. Installation of Back Box
Using the back box as a template, mark the position of the four mounting holes onto the desired location. Drill and
fit rawl plugs or other suitable fixings to hold the back box to the wall. Fix the back box to the wall.
The unit requires mains power and the signal for the energy meter. These cables may be brought into the enclosure
using the large holes on the back wall of the enclosure, or through any of the eight cable gland holes provided
(remove the blanking plug and fit M16 glands as required).
Connect the mains to the Power Supply PCB Assembly using the cable clamp arrangement provided and ensuring
the connections are tight. Note: with Version 1 PSU, the Earth cable should be connected to the pcb terminal, on
Version 2 PSU, the Earth cable should be connected directly to the earth stud on the back-box.
Connect the Volt-Free Pulse Output from up to four Energy Meters to the inputs marked Input 1-4 on the Control
PCB Assembly. See diagram below and Section 3.4.

3.5. LCD Display Installation
After the back-box has been securely fitted to the supporting wall, unpack and carefully fit the LCD Display to the
four nylon pillars using a pozi-screw and nylon washer (provided) on each corner of the LCD Display (do not overtighten).
Plug the ribbon cable into the corresponding connector (J2) on the Control PCB and plug the back-light connector
into its corresponding connector (J1).
Remove the protective plastic covering the LCD Display at this point (3 or 4 strips of plastic).
3.6. Set up
At this point, apply mains power to the unit. Set the Set/Run switch on the Control PCB Assembly to SET.
Use the Menu switch to advance through the following parameters in sequence (see photo below):
When a parameter is flashing, use the Up and Down switches to adjust.
When the unit is set to RUN, all parameters will be stored in non-volatile memory.
See section 3.8 regarding the External Set-up Control Unit.
3.6.1.
Set Pulse Value
The Energy Meters produce pulses which represent Watt-hours (Wh) being generated. The unit needs to
be programmed to set the Pulse Value in Wh. Also, if a number of identical systems are in place but only
one of the systems has energy meters fitted, then the Pulse Value can be multiplied by 1 to 40 to enable the
display to show the energy for the entire arrangement.
First set the number of systems (1 to 40) using the Up and Down switches.
Press Menu.
Now set the Pulse Value (1Wh, 10Wh, 100Wh, 1kWh, 10kWh per pulse).
Press Menu.

3.6.2.
Power Generation Display Unit
User Manual
801309-8.doc
Set Instant Power Time
The instantaneous power being generated is calculated by counting the number of pulses received over a
period of time. This parameter should be set for a time that allows a number of pulses to be received
(which depends on the size of the system and the pulses sent out by the energy meter).
The Instant Power Time interval can be set to 1, 2, 3, 5, 10, 12, 15, 20, 30 and 60 minutes. The
instantaneous power generated will appear on the display after the time selected and then remain
unchanged until the next update.
3.6.3.
Set Total Energy
If a display unit is being installed after the system is up and running or as a replacement, it may be desired
to enter the energy in Watt-hours (Wh) that has already been generated.
The installer may set the Total Energy as any 10-digit number representing Total Energy in Wh.
How to set Total Energy:
When any digit of this parameter is flashing, use the Up and Down switches to change the digit. Use the
Menu switch to advance through all the digits. (The example below shows how to set 1234kWh)
Important: Press the SELECT switch to update the Set Total Energy figure.
3.6.4.
Testing the unit
Each of the Pulse Inputs has a test switch associated with the input terminal connector. By pressing the
test switches the installer may simulate pulses being received and see the results on the display.
3.7. Installation of Acrylic Sheets
Using the eight M4 countersunk screws, fix the rear sheet of acrylic to the back box.
Place the graphic and the front sheet of acrylic onto the rear sheet of acrylic and temporarily fix them together
using the top two M8 fixings.
Apply clear self-adhesive tape all the way round the edges of the two acrylic sheets to seal the two together. This is
important as it can prevent small insects or moisture getting between the two sheets and affecting the appearance of
the graphic and display.
Using the four M8 fixings, fix the bezel in place (note that the front sheet will only be held in place by the adhesive
tape if the top two fixings are removed and the sheet is not supported). The four M8 fixings should be inserted
from the rear and the dome top nut used to secure the front.

3.8. External Set-up Control Unit
Units produced after June 2010 have the facility to connect an External Set-up Control Unit via a 9-way D-type
connector on the bottom side surface of the unit. The External Set-up Control Unit has the same switches as the
Main Control PCB and works in the same way. It allows changes to be made without disassembling the unit.
