Special Instructions For "Safe Use" And Installations In Hazardous Locations; Actuator Mounting - Fisher easy-Drive 200L Instruction Manual

easy-Drive 200L
December 2018
1. The easy-Drive 200L can be installed in any position, but normally the actuator is vertical above the valve. Install the
valve per the manufactuer's guidelines and per any applicable local, regional, and national piping codes.
2. For explosion-proof applications, install rigid metal conduit and seal no more than 457mm (18in) from the actuator.
3. Unused conduit ports must be sealed with an explosion-proof port plug.
Note
Plastic conduit ports provided by factory are to be removed prior to operation and replaced with an explosion-proof port plug.
Special Instructions for "Safe Use" and Installations in Hazardous
Locations
WARNING
To avoid static discharge from the enclosure, do not rub or clean the enclosure with solvents. To do so could result in an
explosion. Clean with a mild detergent and water only.
The enclosure is non­conducting and may generate an ignition­capable level of electrostatic charges under certain extreme
conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external
conditions (such as high­pressure steam) which might cause a build­up of electrostatic charges on non­conducting surfaces.
Additionally, cleaning of the equipment shall only be done with a damp cloth.
To avoid damage to the enclosure, when screws are fully tightened into blind holes in enclosure walls, with no washer
fitted, at least one full thread shall remain free at the base of the hole.

Actuator Mounting

The following procedure describes how to mount an easy-Drive 200L actuator.
The actuator is shipped with the stem in the ideal coupling position; 6% off the lower actuator stop.
Note
Do not stroke the actuator prior to coupling the unit to the valve.
To reposition the actuator to the ideal coupling position calibrate the actuator as valve type "Stop-to-Stop". Ensure the actuator is
able to travel making contact with its internal stops. Once calibration is complete command the valve to 6% open.
User designed and manufactured Mounting Kit and Stem Coupler will be needed to complete this procedure.
WARNING
To avoid personal injury or property damage, keep hands and tools out of the actuator stem travel path when moving the
actuator stem in the following steps.
