Page 6: Intrinsic Safety Considerations
Rev 3 – March 2020 1.2 Intrinsic Safety Considerations The ECD relay’s IS Pilot Terminal is protected by an internal IS barrier. In the event of a phase to pilot fault, this barrier • will clamp the voltage at the pilot terminal to a safe level and protect the relay from damage. However this barrier can only withstand 5.25A for 1s. -
Page 7: Receiving And Storage
Equipment that is found to be damaged or has been modified away from its published specification must not be used. Please contact Ampcontrol if the equipment is suspected to be different than that ordered or if it does not match the published specifications. -
Page 8: Installation
ECD, the conditions of certification will no longer be valid and the equipment will no longer be fit for use in a hazardous area. If any modifications or damage to the ECD is evident, do not use the equipment and contact Ampcontrol for advice. -

Pilot terminal to be positioned at the top while others require the Pilot terminal to be positioned at the bottom. For this reason the ECD relay is supplied with a second loose label with inverted text. -
Page 10: Ecd Relay Overview
The ECD can be configured for latching or non-latching operation and has a remote start option. The ECD relay can also be used as an IS interlock with the pilot terminal connected to a circuit that passes through interlocks and switches. -

Figure 2: ECD enclosure dimensions 4.1.2 Mounting arrangement The ECD enclosure is designed be mounted on a standard 35mm DIN rail. The IS connections are located at the top of the enclosure and the non-IS connections (power and user inputs and outputs) are located at the bottom of the enclosure. -
Page 12: Electrical Connections
Once the ECD relay has been mounted at a suitable location, it is necessary to wire it correctly. Figure 3 shows a typical wiring diagram for the application of the ECD relay. Also refer to drawing ECDM003 for installation information. - Page 13 4.2.6 External Fuse The ECD’s IS Pilot Terminal is protected by an internal IS barrier. In the event of a phase to pilot fault this barrier will clamp the voltage at the pilot terminal to a safe level and protect the relay from damage. However this barrier can only withstand 5.25A for 1s.

Page 14: Commissioning And Calibration
The series resistance measurement can be verified by installing a resistor which is a minimum of 3Ω above the selected trip level, or creating an open circuit, in series with the pilot conductor and verifying that the ECD relay trips within the selected trip time and indicates an open circuit fault. -

ECD’s IS earth terminals. The ECD measures the resistance of this pilot-earth loop (series resistance) and the pilot resistance to earth (shunt resistance). -
Page 16: Remote Start
Latching mode can be selected via the DIP switches at the front panel. When a fault occurs in latching mode the trip will be latched, preventing the ECD from starting (even if the fault is cleared), until a manual reset occurs. -
Page 17: Operation Summary
The user can select the trip time via one of the rotary switches at the front of the unit. The trip time represents the delay after which a trip condition has occurred when the ECD relay will de-energise. The allowed settings for the trip time are 50ms, 100ms, 200ms, 300ms, 400ms, and 500ms. -

LEDs and returning the relay contacts to the default position. 7.5 Starting the ECD When first powered, the ECD will begin checking its internal circuitry as well as the pilot circuit. If no faults are detected within 1.7s the ECD will be ready to start. -

These ‘routine inspections’ must be carried out by suitably trained people with knowledge of the ECD and the systems into which it is fitted. Routine inspections may take the form of either visual-only checks, or visual and ‘hands-on’... -
