4.1.2 Shielding & Earth Resistance
Never rely on using the vehicle chassis as an electrically continuous common ground without first
measuring the resistance between the chosen earth point and the negative battery terminal. The
cabin earth point or the battery terminal.
Not checking the earth resistance could be the cause of intermittent equipment malfunctions with
operational reliability being sacrificed.
The measurement must be taken in the following manner:
•Extend the multimeter lead with a low resistance cable long enough to reach from the battery to
the chosen earth point. The resistance of this cable should be measured and taken into
account when calculating the final resistance.
•Disconnect the negative terminal from the battery and measure from the negative lead to the
point you intend to use as the central vehicle earth point. (The central vehicle earth point is the
point that all TouchStar equipment earth connections are connected to)
•The earth resistance should be measured for each vehicle and must be less than 1 ohm. (i.e.
the earth point resistance less the test lead resistance).
In the event that a resistance measurement of less than 1 ohm cannot be achieved it is necessary
to run a cable from the isolation switch or negative terminal of the battery into the cab for the
vehicle earth. The size of this cable should be equivalent to 65 x 0.3mm, 6mm Auto cable.

T:\HARDWARE & SUPPORT\TSP Products\EMH Manuals\EMH500 Series Installation Manual 2.1a.doc
Earth Resistance Measurement Diagram
Positive Power Connections
The connection to the positive terminal must be treated in the same way. There must be less than
1 ohm resistance between the Positive battery terminal and the positive connection point in the
EJB101. This includes wiring through fuse panels, ignition switches, relays.
Shielding
All shielded cables must be grounded at one end only at the central earth point.
Below 30 meters, one overall shield in multi-core cable is sufficient but above this distance every
cable should be individually screened.
Small millivolt signals should be transmitted by shielded twisted pair wire.
In this case all the register power and data cables must be shielded, and have their shields earthed
in the EJB101.
The shield on the Register cable from the cradle is connected to the shield on the cable from the
EJB 101 junction box. Where this cable connects to the EJB101 junction box the shield is
connected to the ground connection (as is the blue core wire, which is the signal ground
connection, and the red core wire, which is a spare). This is Register Com 1 in the attached
drawing.
The same is true for the shield on the printer comms cable. This is Register Com 2 in the attached
drawing.
The Power cable and the Temperature probe cables are grounded in the same way.
The 1-ohm reading between the EJB101 and the negative battery terminal applies as it does for
the cabin central earth point.
The 1-ohm reading between the EJB101 and the positive battery terminal also applies, as it does
for the cabin mounted equipment

4.1 EMH500 Register
The EMH500 Register has a single cable connection from the junction box to the rear of the EMH500
Register. It is a bayonet style connector and is keyed for alignment.
4.2 Remote Pulser
4.2.1 ERP100 Remote Pulser
The Remote Pulser (ERP100) requires a 6 wire shielded cable connected to CON.104 in the EJB101 and
should be contained within a suitable conduit that satisfies local regulations.
The white plug inside the EMH500 that connects the internal pulser must be disconnected and secured to
the support bracket with a cable tie. Connecting both the internal and remote pulser will cause OPTO errors.
The shield is to be grounded at the EJB and care should be taken within the pulser so as not to interfere with
the rotational operation of the pulser.
The conduit entry is a ½” NPT thread and ½” NPT to 16mm adaptors are available.
4.2.2 Single Pulse Input
If a single pulse is used, connections inside the EJB101 are to P1 and GND with 0.4V and 1.5V thresholds
and single pulse input must be selected in the calibration settings of the EMH500. The internal pulser
connector located on the main board of the EMH500 must be disconnected as above.

5.2 Setting the Average K-factor (KO CAL)
This mode allows the user to manually set or to automatically calculate the K factor. It is required that a
volume be dispensed into a certified measuring container and that this value then be compared to the
reading on the register.
1 From the delivery mode, press CAL to enter into the main menu.
2 K0 CAL? N, will appear with the cursor flashing on the N. This indicates that this option can be changed.
If you are already in the main menu, toggle through the options by pressing TOTAL until this option is
reached.
3 Press TOTAL to toggle this option to Y (for yes). This allows the user to change the K factor.
4 Press STOP/START to enter this option.
5 XXX.XXXX appears on the display with the cursor flashing on the left most digit.
6 To enter a new K factor manually:-
6.1 The new K-factor to be entered must firstly be calculated.
6.2 The user can change the value of the first digit by pressing TOTAL.
6.3 Press RESET to toggle to the next digit and so on for each digit.
6.4 When the K factor has been set, press STOP/START to save this option.
6.5 Press MODE. The display will now read K0 ACN? N, with the cursor flashing on the N. This
option is asking the user if they want to automatically calculate the K factor. Since the K factor
has already been manually set, leave this option as N (for no).
6.6 Press MODE to return to the Main Menu.
7 To automatically calculate the K factor, follow steps 1 to 5, then:
7.1 Press MODE. The display will now show K0 ACN? N, with the cursor flashing on the N. This
indicates that this option can be changed.
7.2 Press TOTAL to toggle this option to Y (for yes).
7.3 Press STOP/START to enter this option.
The display will now show XXXXX.X with the cursor flashing on the left most digit. This is the volume which
was dispensed in the previous delivery, according to the register. This value may differ to the reading on the
approved test tank. Enter the true value of the delivery according to the reading of the test tank.
7.4 Press TOTAL to set the first digit.
7.5 Press RESET to select the next digit, and so on until the true volume reading has been entered.
7.6 Press STOP/START to enter this value.
The register will now calculate the new K factor. This new K factor will momentarily be displayed, followed
by WAIT, then SAVED, before returning the display to the previously dispensed volume measured by the
register. Note that in this procedure, the user was not asked to perform any calculations.
7.7 Press MODE to return to the Main Menu.
8 Press CAL to return to delivery mode.
9 We recommend that a re-test be done using at least three calibration runs to verify the result. If
recalibration is required, repeat steps 1 to 6 (manual calculation), or steps 1 to 7 (for automatic
calculation).
New K-factor = (Register Reading) ×(Old K-factor)

6. Connecting a Ticket Printer
Installation and configuring a ticket printer is dependent on the model of the printer. The EMH500 can
support the following printers:
•TM-295
•CTM-290
•TouchStar Blaster Printer.
Most ticket printers are available in +24V only, therefore a voltage doubler will need to be used if run off a
+12V source. All printers have data connections to the register via the Power Junction Box.
Note: Always mount the ticket printer in the cabin.
6.1 Ticket Printer DIP Switch Settings.
There are 3 Ticket Printer models supported by the EMH500’s software; they are the Epson CTM-290, TM-
295 and the TouchStar Blaster. Following are two tabulated listings for the Epson CTM-290 and TM295
printers.

Check that your Ticket Printer has an ink ribbon fitted.
Set up the comm ports and the printer type in the register (refer to software).
6.2 Installing the TouchStar Blaster Printer
The TouchStar Blaster Printer has no DIP switches therefore once it is wired up, you only have to setup the
register (refer to Software Settings Reference Manual).
Note: Always set the EMH500 to 9600 baud rate when using the TouchStar Blaster Printer.
6.3 Checking the Operation of the Ticket Printer
Supply power to the Register and Ticket Printer, checking for the GREEN (POWER) LED on the printer.
Press the RELEASE button and note that the GREEN (RELEASE) LED appears. Insert your ticket so that
the top of the top line is aligned with the arrow on the side of the printer.
Note: If the ticket is inserted correctly, the RED (PAPER OUT) LED will go out but if the RED LED remains
ON, remove and insert ticket again until NO RED LED is visible.
Perform a delivery run or simply rotate the Register by hand. Print a Delivery Ticket by pressing RESET not
sooner than 6 seconds after the end of the delivery.
Press the RELEASE button on the ticket printer to release the ticket from the printer.
6.4 Connecting multiple registers to one printer.
Connect wires in the following way:
•EMH/EJB’s transmit wires joined together to the receive input of the printer,
•EMH/EJB’s receive wires joined together to the transmit output of the printer,
•EMH/EJB’s ground wires joined together to the ground input of the printer,
•Do NOT join shields of communication cables – each individual cable must have its shield connected to
the ground inside the EJB junction box ONLY.

7. Various DIP Switch Settings
7.1 EMH500 Mainboard DIP switch specifications.
The DIP switches are located under the plastic hood of the register head and approximately in the centre of
the main board. The register will only read the new settings immediately after a power-up.
Dip Switch No. Function
Sw1 By setting the switch to ON, it will ENABLE the erasing option for the internal
software settings. Immediately following power on the display will read ‘ERASE?N’,
press TOTAL and then STOP/START to erase all software settings and re initialise
with default settings. The register will then read “ERASE!”, and scroll “memory
cleared – restart register”. Power the register off then back on again. The “data error”
message will be displayed, to reset the EMH500 to default values press the CAL
button.
Sw2 By setting the switch to ON, it will DISABLE the automatic compensation of
resistance of the temperature probe leads. You have to restart the register after
switching it. The register will then require manual zero-adjustment of temperature
reading. It helps using temp. probe with two wires only, or when resistance of leads
is higher than 2.5 Ohms.
