7. Electric connections
7.1 Inclination transmitter
The inclination sensor is connected via a highly flexible,
shielded signal line with 2 strands and PUR steath. The same
is preassembled at the factory, included in the delivery and
available in different lenghts.

• Do not electricly modify the device nor
carry out any wiring work when energised.
• Do not plug in or unplug electric connection
when energised.
7.2 HART-Signal
The HART signal is directly tapped via the 4 ... 20mA signal
line. The measuring circuit must have a minimum load
of 240Ω. Connect the HART communicator or the HART
modem via cable terminals or the existing communication
sockets of a power supply unit or separator. The connection
is independent of polarity.

8. Electric commissioning
• Provide a separate power supply for the device in case
of consumer loads with high interference levels.
• Install the entire plant in an EMC-compatible manner.
Installation environment and wiring can affect the EMC
of the device.
9. Maintenance
The device is free of maintenance. Repairs may only be
carried out by authorized authorities.

10. Programming
The inclination transmitter may be programmed via HART
modems (e.g. ifak system type isHRT USB) or via HART
communicator (e.g. EMERSON type 475). The cable termi-
nals of the HART modems or communicators are directly
connected to the 4 ...20mA signal line.
• A reset to factory settings is not possible.
• The inclination transmitter must be con-
nected according to the wiring diagram
• The smallest programmable angle is 10°.

Use case 1: Set start and end value
1. S etting zero point (Command 43: Set primary variable zero)
2. Put transmitter into initial position
program 0% = 4 mA (Command 45: Trim Loop Current
Zero)
3. P ut transmitter into final position
program 100% = 20 mA (Command 46: Trim Loop Current
Gain)

Use case 2: Set of fixed measuring range
1. S et zero point (Command 43: Set primary variable zero)
2. Set measuring range
e.g. -15° = 4 mA ... +30° = 20 mA or
-30° = 4 mA ... +30° = 20 mA
