2. Installation and Wiring
Refer to the sensor User Guide for relevant drawings and instructions.
Refer to Sensor Test Certificate for wire colors of the cable.
Refer to the following wiring drawings:
/12 VDC or /24 VDC - DWG W PSX 001 4
/110 VAC or /220 VAC - DWG W PSX 003 4
Relay outputs wiring - DWG S PSX 004 4
2.1 Open the cover of the well/sump/tank. Carefully pass sensor's cable via the
conduit from the well/sump/tank to PS-220.
NOTE:
SENSOR CABLE CAN BE EXTENDED THROUGH AN IP65 JUNCTION BOX.
REFER TO DETAILS IN THE NEXT SECTION.
2.2 Pass a power cable through the conduit from PS-220 to the local power source.
2.3 Option: Pass the appropriate cable via the conduit between PS-220 and the
central control room or remote controlled equipment.
2.4 Connect the Sensor to PS-220, as follows:
Wire color TB6 point TB6 function
Per test certificate 1 DET +12V
Per test certificate 2 DET GND
Per test certificate 3 DET SIGNAL
2.5 In case that a connection with control room or remote controlled devices is
required (through relays and 4-20mA outputs), as well as hazardous area
installation, refer to the wiring diagram.
If Safety barriers are supplied / added:
Wire Color Safety Barrier Contact Contact Function
Per test certificate MTL 7715+ point 3 Sensor +12 VDC
Per test certificate MTL 7715+ point 4 Sensor GROUND
Per test certificate MTL 7710+ point 3 Sensor SIGNAL
Refer to the wiring diagram to see how to connect the Zener Safety Barriers to TB6.
Record the serial number of the sensor connected to PS-220.
