Once the cover is removed the broken glass will be free to be
removed, clean out any other fragments of glass carefully.

To fit the new glass element rotate the test cam clockwise by
an angle of 90º (use test key supplied) this will than allow the
glass to fit back into the pocket it sits in, resting on the pivot
point and test cam, ensure the plunger shaft is resting on the
top of the glass, it might need to be pushed up slightly to
achieve this.

Pivot point Test Cam Plunger Rotate test cam back

Shaft

Upright set point

Whilst lightly holding the glass in place rotate the test cam
back anticlockwise 90º to its original vertical position. The
glass element should now raise up so it is level again
(horizontal) in the viewable window.

Replace the cover plate and tighten the 4 off M4 cap head
screws.

Ensure the glass element is free to move under the cover
plate. This can be done by running through the units test
operation. See section 13 of this instruction manual.

15) End-of-Line and Series Devices

All models can be fitted with series resistors, end-of-line
monitoring resistors, monitoring diodes and zener diodes if
supplied with direct current up to 48Vdc and limited to a
maximum total power consumption no greater than 6.224W.

Min. resistor values and current limitations must be observed
depending on supply voltage and type of components fitted. If
a combination of resistors / diodes / zener diodes is used,
values for all components must be observed and lowest
current limit for either component becomes overall limit.

Current limitation for units fitted with end-of-line resistors,
diodes or zener diodes must be ensured by using a current
limited power supply or fitting a current limiting resistor at the
control panel (not provided).

The following table 2 shows limitations for all possible
variations:

Table 2 : EOL and Series Devices limits

EOL (End of line) device;



resistor – ExxxR



diode – ED1



zener – ExxxZ

Series (In line) device;



resistor – SxxxR



diode – SD1



zener – SxxxZ



LED

Microswitch 1 = M/S 1
Microswitch 2 = M/S 2
The unit can be wired with a maximum of 4 module devices –
see wiring diagram D202-06-211 or D202-06-212

Note:- The maximum voltage stated must not be exceeded,
as the internal resistor modules are rated as compliant with
Ex d according to the units voltage

An optional Ex d LED monitoring module is designated after
the model no as either,
GNExCP7-BG-S-L or GNExCP7-BG-D-L to include an LED
and power limiting resistor
or,
GNExCP7-BG-S-C or GNExCP7-BG-D-C with includes the
LED but where the units current must be limited to 20mA. As
the LED has no power limiting resistor.
