1.2 Device description
The EPE2-Controller (Elektronik Pneumatische Entrestung, type 2) are used for monitoring
the residue discharge of GMVT 805 measuring systems.
The control electronics is designed
for two operating modes. In the
“Stand-Alone residue discharge“
mode the electronics work autono-
mously and during product change
switch off the control air and, time de-
layed, the supply voltage of the flow
computer, using a solenoid valve
(12V, Type MVS1-E11-12).
In the “Restentleerung mit Multi-
Flow (MultiFlow residue discharge)“
mode the SeningTM MultiFlow controls
the residue discharge. The solenoid
valve in the control air can then be omitted. For this purpose the CAN bus connection to the
MultiFlow truck computer is prepared.
The “Stand-Alone residue discharge“ or „MultiFlow residue discharge“ modes are set via
a DIP switch S1 on the REC-1S printed circuit board (see also Figure 6 / page 18).
The EPE2-Controller consists of a
sealed SVC-2S power supply unit
and an REC-1S control board. The
use of the device is limited to prod-
ucts of hazard class AIII, whereby in-
stallation in zone II is permitted. (see
chapter 3.6 “Components overview” /
page 18).
The operating status of the EPE2-
Controller is displayed by a yellow
(power) and a green (status) LED.
(see chapter 5 “Display of the operat-
ing states” / page 31).
The cover can be sealed to prevent manipulation.
If the EPE2-Controller are used as a replacement of the previous EPE controls, then the sole-
noid valve is to be replaced with the one mentioned above (due to different control voltage).

1.3.1 “Stand-Alone residue discharge“ function
The Illustrated EPE2-Controller [11] is fitted with an isolation circuit amplifier and a time relay
and connected as per the electric circuit diagram drawing no. E61.351684 / page 43.
The input circuit (signal from initiator [20]) is monitored for broken wire and short circuit. An
error in the input circuit causes blocking of the output (signal to flow computer electronic me-
ter [12] and to the 3/2-way solenoid valve [21]). The electronic meter [12] is used together
with a mechanical measuring chamber for temperature compensated delivery of mineral oil
products.
The above mentioned time relay is required that fluctuations of the liquid level in the sensing
element causing measurement interruptions (closing of the shut-off valve) deactivate the
elec. meter (interruption of the power supply) not until a delay of at least 8-10 s. The reactiva-
tion of the elec. meter takes place without delay, as well as the interruption of the power sup-
ply to the above 3/2-way solenoid valve [21] and its reactivation.

1.4.1 “MultiFlow residue discharge“ function
Alternatively for control the type approved MultiFlow electronic meter in connection with the
EPE2-Controller can be used. The wiring is made as per the electric circuit diagram drawing
no. E61.351994 / page 44.
The EPE2-Controller is connected via a data bus directly with the MultiFlow electronic meter
[12]. The electronic MultiFlow meter takes over all control functions as per the EPE2. Hence
the 3/2-way solenoid valve [21] of the switching devices is no longer needed.
If the type approved MultiFlow electronic meter together with the EPE2-Controller is used for
control, the 3/2-way solenoid valve [21] for the electric switching device is no longer needed.
For the supply of residual discharge components with compressed air, can be used a sole-
noid valve [22] (DN8 / actuator spring-to-open) or an optional manually operated ball valve.

2 General installation instructions
In addition to the following points listed, you also have to follow all relevant regulations such as
VDE 0165 during set-up, operation and maintenance. Only when the following recommendations
are followed we can guarantee long and trouble-free operation.
2.1 Preventive measures
2.1.1 For preventing accidents (caused by ignition of gases)
Explosive protection ordinances are to be followed!
The EPE2-Controller are NOT
suitable for use in explosive areas. However
installation of the device in Zone II is permitted.
2.1.2 To meet the requirements stipulated by standards
•The wiring must be carried out according to the circuit diagrams supplied. The colours of the
wires correspond to DIN 47100. Please follow the colour codes strictly.
•The electrical installation must be carried out according to EN 60079-14; VDE 0165.
•No additional components must be added to the EPE2 housing, since this would void the de-
vice approval.
2.1.3 To ensure trouble-free operation
•Disconnect the power supply during welding on the vehicle.
•Always mount the cable entries facing to the side or downwards, to avoid water from pene-
trating the housing.
•Unused PG screw joints should be sealed on the device using waterproof sealing plugs.
•Protect the terminal- and electronic housings as well as the plugs against direct water spray
(e.g. from the tyres).
•Install all cables so that they cannot get damaged or kinked.
•Fit all wires with end sleeves.
•All electric connections are made using screw clamping technology. The are to be fed into
the housing through the PG-screw joints provided according to their respective cross section.

If wires have to be trimmed, no cable residues must be allowed to fall into the open unit. This
could cause short circuits on the printed circuit board.
There must never be any connection between the housing/shield and the 0V terminal. Oth-
erwise functional errors can occur.
•Install the solenoid valve upright, i. e. the magnetic coil must point upwards.
2.1.4 To make the job of the service personnel easier
•Install the junction boxes such that they are easily accessible.
•Even the electronic housings should be installed such that they are easily accessible.
•Cables without plug-in connectors may be shortened.
•Slightly lubricate the fixing bolts of the covers prior to installation (e.g. copper paste, graphite
grease). This prevents the screws from corroding and ensures that you can loosen them after
prolonged operation.
2.2 Maintenance
The EPE2-Controller for Meter Draining System are maintenance free. The device must not be
modified mechanically or electronically in any way.
During cleaning with a steam cleaner or with pressurised water, the device should be pro-
tected from the water jet. Never aim the steam jet directly onto the device!
§ We won’t accept liability for any damage caused by water invasion in the equipment caused
by improper cleaning.

3 Commissioning
The EPE2-Controller is factory set so that no adjustments are required rafter installation. Just the
operating mode, switching logic and the sensor type have to be checked and adapted if necessary.
3.1 Adaptation of the operating mode
•A difference is made between the “Stand-Alone residue discharge“ and “MultiFlow residue
discharge“.
•Both operating modes as well as other settings are made via the DIP switch S1 on the REC-1S
printed circuit board (see also Figure 6 / page 18).
The DIP switch S1 settings are shown in the following table.
DIP switch S1
on the REC-1S board
MultiFlow residue discharge
(from MID version 5.00)
1 = ON – With MultiFlow
2 = OFF – No Tes t
3 = ON – Only channel 2
4 = OFF – Reserved
5 = ON |
6 = OFF | CAN-Bus
7 = ON | address = 5
8 = OFF |

3.1.1 Operating modes
The EPE2-Controller are designed for two operating modes.
•In both operating modes the residue discharge switch or sensor is connected with the sensor
input J3 on the REC-1S control board.
(see also drawing no. 61.351684 / page 43 and 61.351994 / page 44)
•The sensor or switch type has to be adjusted as described in paragraph 3.4 / page 16.
3.1.1.1 “Stand-Alone residue discharge“ mode
REC-1S printed circuit board DIP switch S1-1: OFF
•In this operating mode there are 2 switching outputs available.
•The switching output “2“ controls the solenoid valve in the main air feed.
•The “Power Out“ switching output, switches the supply voltage for the flow computer meter
electronics.
•The flow chart of the residue discharge and an exact functional description can be found in
chapter 0 / page 19.
CAN Bus termination resistors
SVC-2S printed circuit board DIP switch S1-1: OFF (termination resistors ON)
•The switch has no effect on function in this operating mode. The selected switch setting is
thus arbitrary.
3.1.1.2 “MultiFlow residue discharge“ mode
REC-1S printed circuit board DIP switch S1-1: ON
•In this operating mode control of the main air is made via the SeningTM MultiFlow. The meter
electronics needs not to be switched separately.
•The “Power Out“ switching output is not switched in this operating mode and can thus be
used optionally otherwise.
•In this case the DIP switch S1-2 on the power supply printed circuit board SVC-2S is to be
set to the “ON“ position.
CAN Bus termination resistors
If the EPE2-Controller is used together with the MultiFlow in a CAN Bus network and operated as
the last device on the Bus, then the termination resistors are to be switched ON.
SVC-2S printed circuit board DIP switch S1-1: OFF (termination resistors ON)
•To activate the termination resistors the DIP switch S1-1 on the power supply board SVC-2S
is to be placed in the “OFF“ position.
•This is only necessary when the EPE2-Controller is the last device in a CAN Bus network !

3.2 Switching outputs in “Stand-Alone residue discharge“ operation
The EPE2-Controller switching device activates the 24 Volt supply of the electronic truck computer.
The level in the metering system is monitored by the attached sensor. An additional solenoid valve
that interrupts the main air supply of the metering system is connected.
3.2.1 Switching output of the solenoid valve for the control air
•The control air is switched off immediately after product shortage is detected.
•The output is designed for the operation of solenoid valves with 12 volt control voltage with a
max. current of 430 mA (order no. MVS1-E11-12).
3.2.2 Power Out switching output for the flow computer
•This output is for controlling the flow computer.
•The deactivation of the output and hence the switching off of the supply voltage of the meter
electronics (flow computer) is time delayed (typically 8 secs ).
•The switching output is designed for a max. switching current of 8 A at 24V supply voltage.

3.3 Switching outputs for “MultiFlow residue discharge“ operation
During operation of „MultiFlow residue discharge“ none of the EPE2 outputs are switched. The
switching information is transferred via the CAN Bus to the MultiFlow, which then takes over the
control.
When setting the “MultiFlow residue discharge “ the DIP switch S1-
2 on the
power supply board SVC-2S always has to be set into the “ON
“ position. Hence
other optional devices can be powered by the flow computer 24V (out) connec-
tion.
3.4 Setting the sensor type
The EPE2-Controller supports 3 types of sensors. The selected switch or sensor is connected to
the J3 input on the REC-1S control board.
The setting has to be made before commissioning via the jumpers Jp4 and Jp5 on the
REC-1S printed circuit board, listed in the following table.
The 3 sensor types have to be supplied with different voltages. This adjustment is made with the
two jumpers as displayed in the table:

3.4.1 Setting the sensor switching logic
REC-1S printed circuit board DIP switch S1-3: ON / OFF
•The switching logic of the connected sensor is defined with this DIP switch (see Figure 6 /
page 18). It can be set whether the switch is an NO contact (in active state switch is closed)
or NC contact (in active state switch is open). The DIP switch is factory set to ON = “0“ ac-
tive.
If an inverted function of the switching signal is required, then the DIP switch S1-3 has to be
placed in the opposite position.
3.5 Further tips for commissioning
•For the commissioning of the residue discharge it may be helpful, if the switching output is
continually switched, independent of the input signals.
•For this the DIP switch S1-2 on the power supply printed circuit board SVC-2S is to be set to
the “ON“ position. The supply voltage (24 volts) is thus always through-connected to the flow
computer connection.
•If the “Stand-Alone residue discharge “ is to be activated, then the DIP switch S1-2 (SVC-
2S) has to be placed in the “OFF“ position. Now the supply voltage for the flow computer
connection is switched according to the input state.
•If a PC or Laptop is available, then the relay can also be switched via the service function.
(see also chapter in DOK-512E).

3.7.1 Residue removal control with MultiFlow
The following description is relevant only for program versions from
5.00 (approval according to MID).
The measuring system residue removal message can be switched on and off with Parameter
3.1.8.5.1. In addition Parameter 3.1.8.5.2 has already been implemented which in a future
version will activate the printing out of a document concerning successful residue removal.
If parameter 3.1.8.5.1 (residue removal control)
is set to “2”, this causes the following new oper-
ating sequence:
After entering all the preset values and pressing
the <START> key again, the MultiFlow checks
whether a product change has taken place be-
tween diesel and heating oil / heating oil with ad-
ditives. If this has happened a corresponding
message is shown about the necessary residue
removal:
If residue removal has not been carried out the
driver must press the <F2>k ey.
A corresponding entry is then made in the log-
book and the display shows the following infor-
mation:
The MultiFlow remains in this operating state un-
til it is switched off, i.e. it will not react to key en-
tries (e.g. >START< , >STOP< etc.).
