7. Electric connections

7.1 Inclination transmitter

The inclination sensor is connected via a highly ﬂ exible,

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. Setting 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. Put transmitter into ﬁ nal position

program 100% = 20 mA (Command 46: Trim Loop Current

Gain)

4. Deﬁ nition of direction of rotation

Use case 2: Set of ﬁ xed measuring range

1. Set 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
