1. Introduction
The Ex-Time 40 is a quartz movement wall clock designed for indu-
strial application in areas with an increased risk of explosion in
zones 1 and 2, in accordance with directive 1999/92/EC (ATEX 137).
2. Safety Advice
These Operating Instructions contain information and safety
regulations which must be followed to ensure safe and reliable
operation of the unit under the described conditions. Failure to fol-
low the information and instructions contained in these Operating
Instructions can have dangerous consequences or may violate
applicable rules and regulations.
Please take the time to carefully read through these Operating
Instructions before you start using the unit.
In the event of any doubt or discrepancies (e.g. due to errors in
translation and/or printing), the original German language version
of the Operating Instructions should be referred to.
3. Faults and Damage
If there is any reason to suspect that the safety or integrity of the
unit has been compromised, then it must be taken out of operation
immediately and removed from the Ex-zone without delay.
Precautionary measures must be taken in order to prevent any
further use of the unit in the Ex-zone. It is recommended that the
unit should be then sent to the manufacturer to be examined.
The safety and integrity of the unit may be compromised by,
for example:

13
- External damage is evident on the housing.
- The unit has been subjected to excessive loads for which it is not
designed.
- Incorrect storage of the unit.
- Damage sustained in transit.
- Correct certification is illegible.
- Functionality errors occur.
- Permitted tolerances or threshold values have been exceeded.
4. Safety Regulations
Use of this unit assumes that the operator observes conventional
safety regulations and has read the certificate in order to eliminate
faulty operation of the unit.
The following safety regulations must be complied with:
- The housing of the quartz mechanism and the battery
- compartment must not be opened within the Ex-zone.
- The battery must only be changed outside of the Ex-zone.
- Additional or spare batteries must not be carried in the Ex-zone.
- Only the "type-approved” batteries as listed in these Operating - -
- Instructions may be used.
- Ensure that Ex-Time 40 units are securely attached
- to the wall.
-
It must be ensured that the clock does not accidentally fall into
zone 0.
- The clock should only be cleaned with a damp cloth.

7. Use and Application / Operating Instructions
Before use, please read these operating instructions very carefully
in order to familiarise yourself with the functions of the Ex-Time
40. For you own safety and information, please read the following
instructions.
7.1 Commissioning
Use an appropriate screwdriver to undo the two screws on the
battery compartment cover (on the opposite side from the quartz
mechanism). Remove the battery compartment cover and insert a
battery of the correct type (LR14) (refer to the table under section
6.1 – Table with type-approved batteries ) into the battery compart-
ment. Please refer to the diagram on the housing to make sure
that battery is inserted with the correct polarity. Refit the battery
compartment cover (the spring faces towards the battery), refit the
battery compartment cover screws and tighten securely. Then use
the white adjusting wheel on the housing of the clockwork mecha-
nism in order to set the correct time.
7.2 Changing the battery
To change the battery, use an appropriate screwdriver to undo the
two screws on the battery compartment cover. Remove the battery
compartment cover and dispose of the old battery.
Insert a new battery (only use type-approved batteries ‘ refer to the
table under section 6.1 – Table with type-approved batteries; check
for correct polarity ‘ check the diagram on the battery housing
). Refit the cover to the battery compartment (the spring faces
towards the battery) and secure it with the two screws. The clock
will now start to run again. Then use the white adjusting wheel on
the housing of the quartz mechanism in order to set the correct
time.
Please ensure that all used and defective batteries are properly
disposed of in an environmentally friendly manner.

7.3 Wall Mounting
An integral metal bracket located on the rear of the clock enables
the Ex-Time 40 to be suitably mounted on an appropriate wall. The
fixing of the unit must be secure at all times and precautionary
measures must be taken to prevent the Ex-Time 40 from falling
into an area classified as zone 0. For reasons of electrostatic
discharge, completely insulated mounting – e.g. on a purely plastic
wall - is to be avoided.
7.4 Time Setting
The white adjusting wheel on the quartz mechanism is used to
make any necessary time adjustments.
8. Repairs
Repair work is subject to the nationally valid regulations and directives.
We therefore recommend that such work be performed by ecom
instruments GmbH, Germany, as all repairs must be examined to
ensure functional safety.
9. Disposal
