6.2 Installation Technical Requirements
6.2.1 When installing the chamber, the flange axis of the chamber side must be perpendicular to the
horizontal plane, and the verticality is within 3 °. 6.2.2 Ensure that the level of the equipment lead
pipe is within 3 °.
6.2.2 Ensure that there are no ferromagnetic particles in the medium that could be attracted to the
controller magnetic rod and affect switching performance.
6.2.4 The fluctuation frequency of the measured medium's level cannot be too large, and the
fluctuation range can’t exceed its permissible action limit.
6.3 Installation Procedure
6.3.1 Place the gasket on the flange sealing surface of the container.
6.3.2 Align the switch flange with the container flange, install flange bolts and nuts, and ensure that
the flange gasket is installed correctly.
7.Debugging
7.1 Preparation for Commissioning
7.1.1 Debugging tools: Multimeter
7.2 Electrical Wiring
7.2.1 Wiring Cable Preparation:The wiring cable shall be outer diameter Ф10mm five-core rubber
sleeve soft wire or rubber cable, one of which is inner ground wire. The other four cores are for a
pair of normally open and normally closed contact lines (using two of them), or for two pairs of
normally open and normally closed contacts wirings.
7.2.2Wiring Procedure
1. Remove the enclosure cover.
2. Wiring according to the wiring diagram, please note that the high-alarm and low-alarm switch
action is reversed, be sure to follow the wiring diagram (see Figure 5) to connect to the correct
terminal. For SPDT form, high report connect a pair of normally open point - common terminal (see
Figure 5-1), low report connect a pair of normally closed point - common terminal.
(See Figure 5-2), for DTDP form, the high report is connected to two pairs of normally open
points-public end (see Figure 5-3), and the low report is connected to two pairs of normally closed
points-public end (see Figure 5-4).
