Frequently Asked Questions - EZM-3735 Emko

How to set the setpoint time?

On the main screen, press the Enter key to display the setpoint value. Use the ▲ and ▼ keys to modify the value, then press Enter again to save.

What to do if the display does not light up?

Check that the power supply matches the voltage indicated on the label. Ensure that the external 1 A fuse is not blown. Check the connections to terminals 4 and 5.

How to access programming mode?

From the main screen, hold the Enter key for 5 seconds. If a password is set (different from 0), the P-r-G screen appears. Enter the password with ▲/▼ and confirm with Enter.

How to use the external Start input?

Connect a mechanical contact (e.g., a switch) between terminals 1 (Start input) and 6 (common). The external start type is configured in the Strt menu (EYP0, TYP0, TYP1, etc.). Refer to the manual for wiring diagrams.

What does each LED on the front panel mean?

The LEDs are: Output (relay active), Hour/Minute/Second (display mode), Pause (timer paused), Set (setpoint modification), Program (programming mode, flashing).

How to clean the device?

Use a cloth dampened with ethyl alcohol or water. Never use hydrocarbon-based solvents (gasoline, trichloroethylene) which could damage the housing.

Can I use the device outdoors?

The device is designed for indoor use only. Do not install it in a corrosive or explosive atmosphere. The front is IP65, but the rear is IP20.

What is the relay lifespan?

The output relay has an electrical life of 100,000 operations at full load (16(8) A @ 250 V~). This corresponds to normal use for several years.

How to reset to factory settings?

There is no direct reset function. You must enter programming mode and manually set each parameter to its default value (refer to the manual for default values).

What to do in case of error or malfunction?

First check the power supply and connections. If the device does not respond, power off the system and contact Emko Elektronik maintenance service: [phone]. Do not attempt to repair yourself.

Supply voltage range must be determined in order. While installing the unit, supply voltage range must be controlled and appropriate supply voltage must be applied to the unit.

There is no power supply switch on the device. So a power supply switch must be added to the supply voltage input.

Power switch must be two poled for separating phase and neutral, On/Off condition of power supply switch is very important in electrical connection.

External fuse that on power supply inputs must be on phase connection.

External fuse that on — power supply inputs must be on (+) connection.
