TROUBLE-SHOOTING
The ICON2000 actuator has passed the functional test performed by Biffi Quality
Assurance personnel.
Warning: The actuator is non-intrusive. The control compartment was
sealed in dry and clean conditions and contains no site
serviceable components. Do not open it unless absolutely
necessary. Unauthorised access will invalidate the warranty.
Warning: Since the control compartment contains a 3.6V lithium battery,
only open it in safe area. If the actuator is located in a
hazardous area, a “hot work” permit must be obtained unless
the actuator can be moved to a non-hazardous area.
If the actuator does not work, before trouble-shooting make sure that:
• the numeric display indicates xx %
• the local selector is not in OFF
• the main supply voltage is the same as stated in the name plate menu
• you move the local selector to OFF and check that the alphanumeric display shows one of
the following messages:
- “normal off”
- “alarm off”
- “warning off”
- “ESD ON off”
- “INT off”
If the above checks are satisfactory try to locate the fault using the diagnostic facilities.
