Elsafe Maintenance and Repair:

 The Sentinel  Series safes require only battery Replacement and some cleaning every once in a while to maintain  operation.

 Do not use any liquids, which can contaminate  electronics while cleaning. Dry soft - cloth and vacuum cleaner is recommended as cleaning equipment.

 When the batteries  become too weak the safe will alert by refusing to close.

 Although these safes are designed to make maintenance and repair as easy as possible, the person performing service needs some basic skills within  mechanics  and electronics.

 Keep in mind  that there is a risk of getting electric shock and damaging  safe components if the procedures for repair and replacement are not followed closely. 

 If the safe is still under warranty you should not attempt to do any repair yourself, as damages caused by improper service work will void warranty replacement.

Initialization:

 The Safe has one micro switch  sensing the locking mechanism's position. When the micro switch  is activated, safe is either locked or unlocked.

 If batteries have been disconnected, the safe must do an initialization to check its status:

• Initialization always starts by the safe attempting to move locking mechanism towards locked position.

•  If safe is unlocked, micro switch  deactivates immediately , locking mechanism retracts back to unloked and display shows open.

• If safe is locked, micro switch  will not deactivate, after a short  while the attempt to move towards locked stops and safe displays clad.  

 There are some factors that could interfere with the initialization process:

• Micro switch  is not activated because locking mechanism is between locked and unlocked position  or CPU-board is not properly mounted.

Safe will display Set   or "------".

To rectify this, make sure CPU  - board is correctly mounted and service open the safe.

• Locking mechanism stuck in unlocked position or motor not connected to the cpu-board.

Safe will not be able to move locking mechanism, consequently will the micro switch   not deactivate and safe display clad  even though it is unlocked.

 To rectify this, make sure locking mechanism moves freely and check motor connection before you reconnect batteries.

Battery replacement :

The batteries are situated behind the keyboard.

This means that the batteries can be changed even while the safe is locked. But keep in mind that if the flex cable between the keyboard and the CPU  is damaged, it might be impossible to open the safe afterwards. Therefore , changing batteries on a locked safe requires caution.

The keyboard unit is fastened to its compartment with six different snaps. Three on the top and three at the bottom. To remove the keyboard, you must loosen the top snaps as described in step 1, 2,and 3 below.

 Be careful when loosening the snaps to avoid damage  on the plastic parts and the enamel paint on the door.

A. Start by loosening the left snap with a small flat screwdriver. Push the left side of the door handle gently to make the operation easier.

B. Loosen the centre snap. 

C. Push the right side of the door handle and gently loosen the right snap. When the keyboard is loose, turn it carefully around to avoid the cable to loosen. The batteries are now facing upwards.

D. Replace all batteries . Make sure they are inserted in the correct direction.

E. Check the safe by pushing Reset. It must display open or clad .

F. Align the lower snaps correctly, tilt the keyboard into position and push the upper edge gently to fasten the snaps . It might be necessary to pull the right door handle a bit to engage the right snap.

Removing back cover and repair :

If External mains  cable is impossible to unplug due to furniture etc. There is spot entail  electric shock hazard when working with outlet and internal mains cables.

A. Remove  the keyboard and remove one battery.

B. Loosen the back cover screws, 

C. Pull the back cover gently towards the locking latch side.

D. Move it out from the door to release it from the locking latch guide.

E. Push the cover towards the hinges to slide it off the extended steel tabs in the back of the door and then carefully remove it.

F. The back cover is now loosened from the door. Follow these rules closely when working on back cover components.

• Touch the safe body to discharge any static electricity before working with electronic components. 

• Do not touch the CPU  - board surface until all power sources are disconnected.

If the safe has an outlet, disconnect the internal mains power  connector as shown in the illustration.

G. Loosen the CPU-board  by loosening the screw and push the snaps away from the board. 

H. Disconnect the flex cable.  

 The contact  has a lock function to avoid the cable being disconnected unintended. Loosen this lock and disconnect flex cable by pulling it straight out.

I. Tge back cover is now separated  from the rest of the safe and you can start troubleshooting and replacing spare parts.

 The CPU-board  is fastened with two snaps as indicated on the illustration. Refer to the next  section for spare parts, technical drownings , circuit diagrams  and troubleshooting.

When you have rectified the problem, reversed order to replace back cover.  Remember  to test the safe after works, both normal  operation and service opening.
