General

ERV-08 timer relays are used in all fields (industry, house, plant etc.) need controlls related to the time.

Usage and Working Principle

Make the connections according to the diagram.
Knob (Time Steps): Time range selection.
knob (t): Time value.
Example: Time is 75 minutes.
Make "Time Steps" knob to 100m (100 minutes) and make “t” knob between 7-8. In this case time is adjusted to 75 minutes.
Note: In order to adjust much sensitive higher time values, set “t” knob by chronometer in low stages and increase the stage to the time required.
Example: Time is 25 hours.
"Time steps" knob to 10s (10 seconds) and “t” knob between 2-3. Make power on and check with a chronometer for 2.5 seconds. If it is high or low, set “t” knob again. Re-check the device. Make the "Time steps" knob 100h(100 hours). In this case, you set it more sensitive. After setting the time, power on the device. Device will start timing and meanwhile led switches on-off. When device is timing contact out is (NC) 1. When the timing finish (set time is up) relay led light is switches on and contact out is (NO) 3. Device keeps stable till the power is off.
