DSN-CMZ CMY Indoor Electromagnetic locks For Switchgear

Working principle of DSN-CMZ CMY Electromagnetic locks

Inside the box transformer substation, the ring net switch cabinets under the condition of charged, the input of the voltage signal into electromagnetic lock, a charged indicator, electromagnetic lock can’t open the lock, the box-type substation, ring net switch cabinets and low pressure switch cabinet internal loss of electric power, no voltage signal input end of electromagnetic lock, electric light is extinguished, electromagnetic lock can be unlocked. With functions of charged two directives and atresia.

Using the environment conditions

1. Ambient temperature: up to +40 ℃
2. Lower the general area -10 ℃, -25℃ alpine region

3. Altitude: not more than 1000m above sea level Area

4. Humidity: relative humidity of air on average less than 95%, on average less than 90%;

5. Environmental conditions: no significant contamination, non-flammable, explosive, chemical corrosion and salt spray spaces and no recurring violent vibration.

6. Structure features: adopts integral structure, installation without separating the panel and lock body

7. Execution standard: JB/T7827-95

Electromagnetic lock installation steps

1. in order to unload panel installation M5 nut on the screw, spring washers, flat pad;

2. from outside the cupboard door lock body lock side in the open hole first, then turn the lock body on the panel on the installation of the screw into the cupboard door open good Ф 6 mm hole, and the lock panel and cupboard door plate stick flat;

Inside of door of cupboard of park of 3, from in turn plain washers, spring washers, M5 nut installed on the panel of the M5 screw, finally tighten nut M5.

The use instructions of electromagnetic locks

(1) normal lock instructions

A. charged light is put out, lift the button, turn the handle towards the lock open clockwise direction (left or right counterclockwise), continue to exert oneself to do, when to limit position lock switch will automatically lock the lock open position, need to artificially will turn the handle to open the lock in the opposite direction, namely lock return to lock in position, so as to meet the blocking state.

B. charged indicator, lift the button, the handle cannot turn, electromagnetic lock can’t open the lock.

Operation method: pull the handle

(2) manual unlock step:

A. emergency unlocking hole to insert the unlock key, turned the key in the direction shown by the panel instructions 90 DHS to “A” or “A”,  anchored off A lock of moving iron core block;

B. lift the button, turn the handle towards the lock open clockwise direction (left or right counterclockwise), continue to exert oneself to do, when to limit position lock switch will automatically lock the lock open position, can open cupboard door.

Note: to unlock the key to unlock process, it is anchored off a lock of moving iron core block, to remove the effect of blocking state, and the lock must use the handle to open mobile lock, achieve the lock, so you can ‘t directly with the unlock key lock.

Models and meaning

Note: The so-called installed the left or right, series operator lock the object oriented (such as lever, cabinet put oneself in another’s position fixed part), and the corresponding installation position When electromagnetic locks in the lock on the object location, located in the operator to the left is on the left side of the installation, on the other hand, is on the right side of the installation.
