4.3.2 Setting the controller type
Setting controller type
Selection can be made among three controller types to define the basic control action to be performed: control-
ler UA 111 X, UA 111 XP and UR 141. Each controller is identifiable by a six−digit Device No. stored in the EE-
PROM. The software version is identified by a Version No. stored in the EPROM (Menu 6−2−1).
Functions not required by the selected controller type are hidden. When changing the controller type, all para-
meters are restored to their basic settings. The controller type can be set by Coding Switches 1 .. 3 of DIP
Switch S3. Only part of the overall functions and parameters contained in the UA 300 D are available when se-
lecting a specific controller type.
Operation of the controller with a non−supported DIP switch setting is not allowed.

Settings made on DIP Switch S3 do not become effective on the UA 300 D until the controller is brie-
fly switched off and then back on!
4.3.3 First start – Loading basic settings
First start (which replaces all parameters by the bsiac values) can be performed as follows:
1 Select a different controller type (see also Section 4.3.2).
2. Briefly switch controller off and back on.
3. Wait about 1 minute for controller to start up.
4. Set the required controller type (after first switching the controller off for safety reasons).
5. Again briefly switch the controller off and back on.
New start is also performed after exchanging the EPROM between the controller versions
UA 300 ´ UA 300 D ´ UA 300 E ´ UA 300 L.
EPROM replacement must be carried out only by trained personnel or at the manufacturer’s works.
Improper replacement of the EPROM can result in damage to the controller and impairment of con-
troller functions.
Operation of the controller with a non−supported DIP switch setting is not allowed.
