Honeywell 10310/2/1 Earth Leakage Detector Module
10310/2/1 Earth leakage detector (ELD)
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).
An earth fault sets the flip-flop (FF), and de-energizes the relay. The flip-flop remains set until a reset is given. This can be done in three ways:
• manually (by setting switch 2 to 'RESET' position), or
• by a high level at the Rst24 input, or
• by a high level at the Rst110 input.
The ELD module can be tested by connecting a 1.5 kOhm resistor between 0 V and earth. This should set the flip-flop. A 1.5 kOhm resistor in the ELD with its own connection to earth (on the Earth2 pin) allows testing of the ELD and the earth connection (switch 2 in 'TEST' position). A disconnected Earth1-to-Earth2 link will block the flip-flop set action (because no earth current is flowing).
