Electrical Connection - Icon Process Controls Level Pro UltraPro 500 Series Instruction Manual

ULTRAPRO 500 MANUAL
Ultrasonic level meters
• If the level sensor is mounted to bottlenecks and places with
barriers, or near uneven walls or the filling area, where the
transmission signal could be distorted, we recommend using
a guide tube (acoustic horn). The tube must be made from a
single material with a smooth inner surface (see image 14a,
14b ). The minimum tube diameter must have the dimension
„b" according to image 4
9. ELECTRIC CONNECTION
Connection through ISO connector
The UPS level meter or ULS level sensor with a G type cable gland are connected to
processing (display) units by means of a cable with an outer diameter of 6 to 8 mm
(recommended wire cross-section 0.5 to 0.75 mm2), via a detachable ISO connector
with inner screw terminals, which is part of the delivery. The connection diagram and
the inner view of the connector are shown in Fig.15 and 16. Non-detachable connector
IP67 with PVC cable 5 m long can be supplied as an extra option.
Connecting the cable to the device:
1. Unscrew the connector from the device body using a
suitable screwdriver.
2. Remove the inner part of the connector using a flat
screwdriver (insert the screwdriver in the gap marked with an
arrow).
3. Unscrew the cable gland and pull the supply cable inside
the connector.
4. Connect the cable wires to the screw terminals as shown in
Fig. 15 (current output 4-20 mA), Fig. 16 (voltage output 0-10
V), Fig. 17 (S type output) or Fig. 18 (P) type output. Tighten the
terminals firmly.
5. Insert the terminals back in the connector so that the NC
terminal points away from the cable gland. Fasten the cable
gland.
6. Check the sealing on the connector and attach the
connector back to the device body.
