II 2GD

The identification label should be as follows:

2Use

This EEx d switch box may only be used in Zone 1 and 2

areas. It may be used with flammable gases and vapours

associated with apparatus groups IIA, IIB and with

temperature classes T1 to T6 in the ambient temperature

range -20°C to +55°C.

The equipment is only certified for use in ambient

temperatures in the range -20°C to +55°C and should not

be used outside this range.

Be sure that the switch box is used only within the product

2.2.1 Important safety procedures

a) Before carrying out any form of installation,

dismantling or maintenance on the actuator

or switchbox, ALWAYS disconnect all air and

electrical supplies.

b)Electrostatic Hazard. Clean only with a damp

cloth.

c) When replacing any items, use only HYTORK

supplied components and suitably qualified

and competent personnel.

3 Fitting the SafeVision

1 Attach the proper mounting platform or mounting

bracket to the SafeVision using the bolt and washer

sets provided. When using Safemount mounting

platforms, place the platform centrally along the base of

the SafeVision housing and secure the bolts for one of

the bolt mounting patterns.

2 The SM 80-20 platform will fit Hytork actuator models

with a 20mm high Namur pinion & the VDI/VDE 30mm x

80mm bolt pattern.

3 The SM 130-30 platform will fit Hytork actuator models

with a 30mm high Namur pinion & the VDI/VDE 30mm x

130mm bolt pattern.

4 Operate the actuator to the fully closed position.

5 Attach the SafeVision and mounting platform/bracket to

the actuator, locating the tang drive of the SafeVision

drive shaft correctly in the slot on top of the actuator

drive pinion.

6 Secure complete assembly using bolt and washer set

provided.

4 Removing the cover

1 Unscrew the eight cover to base securing screws

located around the SafeVision housing until all the

threads are disengaged from the base assembly.

2 Lift the cover assembly, complete with visual indicator

display, upwards and away.

3 The switches, terminal rail and switch setting cams are

now fully exposed.

5 Important wiring installation 7 Replacing the cover

- All electrical wiring must be carried out in accordance

with Local and National Electrical Standards and

Codes. i.e. EN 60079-14 (1997) or IEC 60079-14

(1996).

- The proper wiring diagram for each unit is located

inside the SafeVision housing. Check that the correct

wiring diagram has been included and follow the

diagram carefully.

- Connect with wiring 0.5 mm2 to 2.5 mm2, check that

the wires are properly inserted into the terminal block

and that all terminal screws are tight.

- Ensure that the internal earth (Ground) wire is

connected to the screw on the Switch/Terminal block

plate using a suitable crimped lug.

- Ensure that the external earth (Ground) wire is

connected to external earth stake using minimum 2.5

mm2 wiring and a suitable crimped lug.

- All unused cable entries are to be sealed using suitable

ATEX approved blanking plugs.

6 Setting the switches

1 Each switch has its own independent cam arrangement.

2 Lift the bottom cam against the spring to disengage it

from the drive spline and turn it until the switch is

activated. Once in the correct position, push the cam

back on to the spline.

3 To set the other cam, operate the unit to the opposite

end of its travel and adjust in the same manner.

4 Operate the unit fully in both directions several times to

check that the switches are operating correctly.

1 Confirm the final position of the actuator / valve.

2 Ensure that the visual indicator display coincides with

the position of the valve and that the drive tang on the

indicator drive shaft, is in the same orientation as the

slot on the switching drive shaft.

3 Replace the cover assembly with the two shafts

engaged correctly and tighten the eight cover to base

securing screws.

4 Operate the unit fully in both directions several times to

check that the visual indicator is operating correctly.

5 If repositioning of the visual indicator display is required

for orientation, unscrew the stop screw and rotate the

outer cap anti-clockwise by 15 degrees. Lift the cap to

remove it.

6 Reset the indicator by lifting and repositioning on the

drive shaft. Replace the outer cap and retighten the

screw.
