14. HI-VIZ INDICATION OPTION

14.1. Installa on instruc ons
Note this device will not operate correctly on AC.
DANGER
!
Danger of explosion when used in explosive atmospheres (only in the event of a fault in zone 2)
Opening the control top in an explosive atmosphere is only allowed in a non-energised state
When upgrading an exis ng F783E installa on do these things first:
Remove the control head cap and discard it. The upgrade kit will have the cap with lens and O-ring already fiVed.
Isolate the air supply to the control head before removing the two m6x30 caphead screws which secure the control head to the
actuator or adaptor. Replace these with the two long stepped fixing screws (supplied in kit). To ensure the two O-rings under the
control head are not dislodged in the process, replace one screw at a )me. Tighten the two screws to 3.5Nm.
Disconnect the proximity switch leads from the module.
Con)nue as if from new as below.
Assembling the F783E Hi-Viz unit c/w F783E Control head and Module:
Follow the instruc)ons for assembling the F783E control head on the
actuator up to the point of fiBng the two M6x30 capscrews. Use
instead the supplied long capscrews from the Hi-Viz kit box.
Tighten the two screws to 3.5Nm. Remove the Hi-Viz unit from its
packaging and push it down over the caps of the long fixing screws un)l
it clicks into place. The Hi-Viz unit should be oriented such that the two
cable connectors are on the same side as the module.
CAUTION - the LED's are very bright, do not look directly into the top of
the Hi-Viz unit when it is powered.
Connect the proximity switches to the Hi-Viz unit where indicated, and
connect the loose leads from the Hi-Viz unit to the module, the Closed
switch should connect to the header marked RED on the Hi-Viz unit, and
the loose lead on the same side of the unit (R) connects to the module
Closed header. Similarly for the Open switch lead (G).
Restore the air supply to the control head and if it is safe to do so, test
the opera)on of the indicators by cycling the actuator. Confirm the Red
posi)on LED is ac)vated on both the module and the Hi-Viz unit
together, and likewise the Green LEDs. Fit the new control head cap.
The valve posi)on indica)on will now be visible through the relief valve lens.
14.2. Fault finding and servicing the Hi-Viz
Fault Finding:
If there is no indica)on on the Hi-Viz LEDs, check the plug connec)ons between the switches and the Hi-Viz unit, and between
the Hi-Viz unit and the module.
If the wrong colour is indicated on the Hi-Viz (for example Red while Open and Green while Closed) swap the two cables from
the proximity switches to the Hi-Viz headers.
Servicing:
The only serviceable components are the O-rings, to ensure the IP ra)ng of the cap, all replacement O-rings must be sourced
from an authorised PENTAIR supplier. Remove the cap and gently push the lens upwards slightly from the inside, hook out the
old O-ring and replace with a new one. Allow the lens to return to its sealed posi)on, pop it up and down a few )mes to be sure
it is seated correctly.
