All technical data in this list relate to the state at the moment of edition. We reserve the right
for technical improvements and changes at any time.
ATTENTION!
Please read these mounting instructions before starting the installation. Mounting, electrical connection and test must only be carried out
by trained staff that have read these instructions and have a full understanding of their content. Before installing the system the user has
to decide if the suggested key transfer plan solution fulfils the application requirements and that the gates are secured according to the
relative standards. The suggested key transfer plan has been designed and forms one solution based on the requirements as advised to
Dold.
For a safe installation all the available mounting points must be used. When making changes to an existing system please take care to follow the
mounting rules as described in this document. Do not remove or re-adjust any parts inside the (electrical) units. Please note that the mechanical
modules have two cleaning holes. Please make sure that at least one hole remains open so that dirt can exit. Please make sure that appropriate
seals are used for all the cable entries. The connection (integration of electrical modules) must be carried out according to the required safety
category DIN EN ISO 13849-1. A validation in conformity with DIN EN ISO 13849-2 is mandatory. Before starting the system it must be checked for
function according to the corresponding key transfer plan. After completing the tests the covers of the electrical units must then be fitted and fixed
with the appropriate screws. Maximum torque = 1 Nm ±0.1 Nm. Please make sure that the front covers of the electrical units are mounted properly
before operation. Only when the lids are mounted correctly, function and protection class will be as specified.
It is recommended to carry out planned maintenance min. twice a year to remove dirt and other contaminants from the units to keep the system
working correctly. In case of intense fouling, cleaning should be carried out more often.
ATTENTION!
Do not use grease for lubrication! If lubrication is necessary (see 6. lubrification) for chosing the lubricant.
Please also pay attention to the standards DIN EN ISO 14119, DIN EN ISO 13849-1 and DIN ISO 12100.
For correct mounting and usage of devices with Auxiliary-, Emergency-, or Escape release, refer to the requirements of DIN EN ISO 14119
Please contact DOLD if you have any doubts or questions regarding the installation.
Take notice of the requirements of EN ISO14119:2013 in reference to foreseeable manipulation, especially to §7.1 and 7.2
Upon installation electric modules must be connected to the ground, to avoid any potential differences.
The statements and safety notes contained in these mounting instructions must be strictly adhered too.
The type identification of a combined unit is built up from the bottom module to the top.
Mechanical key module numbers are added together, e.g. on a mechanical lock with 2 keys to be inserted (10 + 10) and one to be extracted (01).
This sums up to be 21. At the upper end of the mechanical guard lock an actuator module (A) is required. The type reference for this assembly is
then, M21A.
An M module should always be mounted on the open end of a unit.
If a key module 10, a padlock module W or an actuator module K is mounted directly on a switch or on a solenoid locking switch, the position of the
key or actuator has to be monitored for category 3 or 4 as shown in wiring examples 3 and 4 on page 15 and 16.
Above a B, D, K and E actuator module there should always be mounted one or more mechanical modules or an M end module.
Below A, B, D, K and E actuator modules there should always be mounted one or more mechanical modules or an electrical module.
Products of the SAFEMASTER STS plastic series are indicated with a /K at the end of the type name.
Example: M10A/K, Key module 01/K, Actuator module B/K, End module M/K.

The STS-system made of stainless steel can be within limitation used as mechanical stop.
Follow values must not be exceeded:
•F = 50 N
•v = 500 mm/s
ATTENTION!
The STS-system made of plastic must not be used as mechanical stop.

1. When the machine is in safe mode and the solenoid lock is released,
the 1st key can be removed.
2. Removal of the key can be monitored and a signal can be
integrated into the machine control.
3. Key is inserted into mechanical lock.
4. Hatch 1 can be opened
5. Only when the 1st key is removed, the 2nd key can be obtained.
6. 2nd key is inserted into mechanical lock.
7. Hatch 2 can be opened.
To restart the machine, steps 7-1 have to be processed in reverse order.
Both keys have the same code and can operate both covers.
