Product Details:

The 10310/2/1 module is an earth leakage detector (ELD) for 24 Vdc systems. It has a manually operated self-test and earth connection monitor (switch 2 in 'TEST' position). The ELD can be used to monitor:

• 24 Vdc, 48 Vdc and/or 60 Vdc systems , or

• 110 Vdc systems.

The ELD module connects earth level with –12 Vdc (referenced to the 0 V connection of the 24, 48, 60 and/or 110 Vdc supply). This connection is:

• continuous (switch 1 in 'DC' position), or

• interrupting at 1 Hz (switch 1 in '1 Hz' position), or

• interrupting at 0.25 Hz (switch 1 in '1/4 Hz' position).

With switch 1 in the '1 Hz' or '1/4 Hz' position, the green 'MODE' LED on the module front flashes at the selected connection frequency.

Switch 1 is normally used in the 'DC' position.

The '1 Hz' position should only be used to accommodate for solenoids or relays that could stay energized by the negative earth voltage. The '1/4 Hz' position can be used for locating earth faults. Locating earth faults requires a current clamp (e.g. the C37 clamp from Chauvin Arnoux) and a voltmeter (200 mV AC range).
