◆ Electrical connection diagram and terminal diagram of ultrasonic level difference meter:
Relay: RLlnA and RLnB are normally open, RLnA and RLnC are normally closed
Wiring method:
Grounding: First, the ground terminal of the meter must be connected to the ground. Do not share the
ground terminal with other equipment. Connect to terminal 4.
Current: c connected to mA n + current-connected to mA – / GND n = 1 for single probe, n =
1,2 for double probe
Transducer: Red line: Connect to Trans_n Transducer n Blue line: Temp n + Temperature
Black wire: GND ground wire n = 1 for single probe, n = 1,2 for double probe
For single probe, n = 1,2, for double probe, n = 1,2,3,4 Power cord: AC, connect L, N
DC: 24V + to 24VDC +, GND to 24VDC-
Remarks: ① Relay 1 is used for probe 1 alarm, relay 2 is used for probe 2 alarm, relay 3 and relay 4
are used for difference alarm.
★ In the dual-level working mode, mA 1+ and mA- output probe 1 current, mA2 + and mA- output
probe 2 current.
② ★ mA1 + and mA－ output the difference current. mA2 + and mA-output the current of probe 2 by
default, and can also choose to output the current of probe 1 (selected in "9 working mode"-"2 mAOut
2 output").
