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 top cam clockwise by
an angle of 50º (use a 6mm Allen key) this will than allow the
glass to fit back into the pocket it sits in, resting on the pivot
point and test cam, release the top cam to rest on the top of
the glass element.

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.
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 1 shows limitations for all possible
variations:
* note :- EOL and series resistor values are listed
as the minimum resistor value allowable at the
specified minimum wattage.
