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 Sening
TM
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).
