adjusted me t, the counted me is erased. The me is restarted when

the triggering signal is applied again.

F OFF Delay: When the supply voltage is applied, the output relay

switches into ON posion and the adjusted me t is started to count.

The output relay switches into OFF posion at the end of the me t.

This status remains unl the supply voltage is interrupted. If the supply

voltage is interrupted before the expiry of the adjusted me, the me

already expired is erased and is restarted when the supply voltage is

applied again.

G Symmetric Flasher: When the supply voltage is applied, the

adjusted me t is started to count. The output relay switches into ON

posion at the end of the me t and the adjusted me counts again.

The output relay switches into OFF posion at the end of the me t.

This cycle counnues ll the supply voltage is interrupted.

① Time Mulplier Adjustment: It is the me mulplier that the

selected me range is mulplied. It is set from 0.1 to 1 with the

adjustment trimpot on the device.

②Time Range Adjustment: It shows the maximum value of the

is started to count. Aer the adjusted t has expired, the output relay

switches into ON posion. This status remains unl the supply voltage

Do you have a question about the Entes MCB-20 and is the answer not in the manual?

The MCB-20 Time Relay is a versatile device designed for both industrial and domestic applications. It operates within a wide voltage range of 12-240 VAC/DC and offers an adjustable time range from 0.1 seconds to 100 hours, along with seven distinct timing functions.

Function Description

The MCB-20 features three main adjustment points:

Time Multiplier Adjustment: This trimpot allows for fine-tuning the selected time range, multiplying it by a factor between 0.1 and 1.
Time Range Adjustment: This setting determines the maximum value of the selected time range. Users can choose from eight different time ranges to suit their desired operation time. The operation time is calculated as "Time range x Time multiplier." For example, to set an operation time of 30 seconds, one might choose a time range of 100 and a multiplier of 0.3 (100 x 0.3 = 30 seconds).
Function Adjustment: This selector determines the specific timing function the device will perform. The available functions are:
- A ON Delay: When the supply voltage is applied, the device starts counting the adjusted time 't'. Once 't' expires, the output relay switches to the ON position and remains there until the supply voltage is interrupted. If the supply voltage is interrupted before 't' expires, the counted time is erased and restarts when the supply voltage is reapplied.
- B OFF Delay with Control Input: With both supply voltage and a triggering signal applied, the output relay switches to the ON position. When the triggering signal is interrupted, the device begins counting time 't', and the output relay switches to the OFF position once 't' expires. If the triggering signal is reapplied before 't' expires, the counted time is erased and restarts when the triggering signal is interrupted again.
- C Single Shot Leading Edge with Control Input: Upon application of both supply voltage and a triggering signal, the output relay immediately switches to the ON position and begins counting time 't'. The output relay then switches to the OFF position once 't' expires. During the adjusted time, the triggering signal does not affect the device's operation. After 't' expires, the triggering signal initiates the next cycle.
- D Single Shot Trailing Edge with Control Input: When the supply voltage is applied, the triggering signal has no immediate effect on the output relay. When the triggering signal is interrupted, the output relay switches to the ON position and starts counting time 't'. The output relay then switches to the OFF position once 't' expires. Similar to function C, the triggering signal does not affect the device's operation during the adjusted time. After 't' expires, the triggering signal initiates the next cycle.
- E ON Delay with Control Input: When both supply voltage and a triggering signal are applied, the device starts counting time 't'. The output relay switches to the ON position only after 't' expires, and this state persists until the supply voltage or the triggering signal is interrupted. If the triggering signal is interrupted before 't' expires, the counted time is erased, and the time restarts when the triggering signal is applied again.
- F OFF Delay: When the supply voltage is applied, the output relay switches to the ON position, and the device starts counting time 't'. The output relay switches to the OFF position once 't' expires. This state remains until the supply voltage is interrupted. If the supply voltage is interrupted before 't' expires, the counted time is erased and restarts when the supply voltage is reapplied.
- G Symmetric Flasher: Upon application of the supply voltage, the device starts counting time 't'. The output relay switches to the ON position after 't' expires, and then immediately begins counting 't' again. The output relay switches to the OFF position after this second 't' expires. This ON/OFF cycle continues symmetrically until the supply voltage is interrupted.

Usage Features

The MCB-20 includes visual indicators for its status:

Supply LED: Illuminates when supply voltage is applied and extinguishes when interrupted.
Relay LED: Illuminates when the output relay is in the ON position and extinguishes when it is in the OFF position.

Maintenance Features and Precautions

To ensure safe operation and longevity of the device, the following precautions and maintenance guidelines should be observed:

Safety First: Always disconnect all power before working on the equipment to prevent death or serious injury.
Front Panel: Do not remove the front panel when the device is connected to the network.
Cleaning: Do not clean the device with solvents or similar substances. Use only a dried cloth for cleaning.
Wiring: Verify correct terminal connections during wiring.
Servicing: Electrical equipment should only be serviced by a competent seller.
Mounting: The device is designed for panel mounting.
Load Considerations: The contact resistance at ohmic load (e.g., incandescent bulbs, resistance devices) is 8A. For inductive loads (e.g., AC motors, fluorescent lights) or capacitive loads (e.g., LED drivers, UPS, electronic ballast fluorescent lights), it is recommended to use a contactor. Failure to do so may lead to adhesion in the relay contacts.
