    Section Three Installation D. L3610R Electrical Connections (Remote Units) The Model L214 tri-axial cable connects the probe to the L3610R electronic chassis through two three-connection terminal blocks. One is located on the circuit board of the L216 Remote Head. The other is on the electronic chassis mounting plate inside the plastic NEMA 4X housing. Refer to Figure 3-5 for the wiring diagram.

  • Page 19: Ground Isolation

    The standard L3610 unit is shipped from the factory without ground isolation. If ground isolation is required, it can be easily provided in the field by cutting open the ground isolation jumper wire (JA1) and connecting a Ground Isolation Capacitor between the G and the SIG - terminals on the terminal block.

    2. Apply power to the unit and allow a 15-minute warm-up time before performing the operational checkout of the equipment. 3. The “A” and “B” LED Diagnostic Indicators, located on the top panel of the L3610 chassis (see Figure 4-1), should be in the OFF (not illuminated) state. Refer to section 4.E for a functional description of these LED indicators.
