Safety
WARNING
Dangerous voltage!
Electric shock could kill or seriously injure.
- All work on the device must be performed by a fully qualified electrician.
- Ensure that the mains voltage matches the voltage marked on the device.
- Ensure that the device is provided with its power supply line and electric fuse.
- The device may not be used in aggressive environments, in atmospheres in which there are chemically active substances.
- The output port and internal electrical elements of the device must be protected from the humidity.
NOTICE
- De-energize the device before working on it. Switch on the power supply only after completing all work on the device.
Mounting
To mount the device:
- Prepare the mounting cutout with Ø of 22.5 mm in the switchboard where the device should be mounted (see Fig. 2).
- Carefully position the supplied gasket (see Fig.
- Place the device with the installed gasket in the prepared mounting cutout and tighten the nut (included in the scope of delivery) to fix the device.
NOTICE
Do not use any tools to tighten the nut. Tighten the nut only by hand.
Removing proceeds in the reverse order. 
Connection
General information
Signal cables should be routed separately from the power supply cables as well as from the cables which are sources of high-frequency and impulse interference.
- For high-quality clamping and reliable electrical connections, it is recommended to use:
- copper multicore wires, diameter after tinning – 0.9 mm (17 cores, AWG 22) or 1.1 mm (21 cores, AWG 20);
- copper wires with single-wire cores, diameter from 0.51 to 1.02 mm (AWG 24-18).
- The ends of the wires should be stripped of insulation by 8 ± 0.5 mm (see Fig. 4) and, if necessary, tinned.
Wiring
CAUTION
To protect the device input from the influence of industrial electromagnetic interference, the “device-sensor” communication lines should be shielded. To protect the device input circuits from possible breakdown by static electricity charges accumulated on the “device-sensor” communication lines, their wires should be connected to the shield ground screw for 1–2 s before connecting to the device terminal block.
Connect the “device – sensor” communication lines to the primary converter and the device input and connect the device to the power supply (see Fig. 6).
Fig. 6 Wiring diagram
To protect the device against microseconds’ impulse noise of the output device (open collector) on the terminals “DO” and “-“, it is recommended to use connecting lines no longer than 30 meters or install devices for protection against impulse noise on the DC line. The VD1 diode should be located as close as possible to the terminals of the relay winding. The parameters of the diode are selected in accordance with the following rules:
The forward current of the diode must be at least 1.3 R1 (1.3 of the relay coil current).
Indication and control
- The 4– digit and 7– segment indicator on the front panel is designed to display measured values, alarms and device parameters. The segments of the digital indicator can light up in one of the following colors (see Section 13):
- green;
- red;
- yellow.
There is a micro-USB connector on the bottom of the enclosure.
Error indication and remedy
Being powered the device starts to operate. If the indicated values do not correspond to the real measured values, check the following:
- sensor function and communication line integrity;
- correctness of sensor connection;
- settings of scaling parameters (di.Lo and di.Hi).
