iv Remove the cable ties at both ends of the energy
chain to gain access to the retaining screws securing
the energy chain, remove the screws and take off
the chain and loom assembly taking note of loom
routing for replacement.
v Replace the new chain and loom assembly by
reversing the above ensuring all looms are routed
correctly and secured as found and clear of moving
parts. Then test all table functions.
6.6.18 Break gearbox loom
To replace a break gearbox loom (item 19 of Fig. 6.7)
proceed as follows:
i Remove the head and leg section and then the trunk
sections as detailed in section 6.2.5 noting the
warning at the beginning of section 6.2.5.
ii Remove the cross beam top cover (item 10 of Fig. 6.7)
to gain access to the break gearbox loom securing
screws. Remove the ‘P’ clips and connections to the
break potentiometer, the three actuator PCA and spade
connections on the break motor.
iii Replace the loom, remake all connections and
secure the loom as found. Check Appendix 2 and
proceed as detailed in the ‘Application software
manual’. Reassemble the table and carry out a full
table function test.
6.6.19 Batteries, table and handset
6.6.19.1 To replace the table batteries, in the pedestal
base, refer to section 6.3.2 and replace them as a pair
(main or standby) also see 6.6.26 to recondition the battery
management system if required.
6.6.19.2 To replace the batteries in the infrared
handset proceed as follows. Note: Service kit part number
111040 (UK side rails ) or 111745 (Denyer side rails)
contains all the required parts, including a new spring clip
and screws, also see section 6.6.23.1.
i Remove the six screws from the back of unit and
carefully separate the front and back moulding, noting
that the internal PCA is connected to both mouldings.
ii Remove both batteries and always replace both as
a pair. Ensure the new batteries are replaced in
accordance with the markings (+/-) in the moulding
recess.
iii Replace the waterproof seal with a new one and
ensure that it is in place within its seating (this is
required to ensure the IP rating is not compromised).
Check the connection on the PCA from the battery
leads and the overlay are in place and that the PCA
is resting on the moulded ledges near the batteries
and correctly positioned over the two circular posts
at the opposite end, before clipping the back and
front mouldings together.
iv Replace the securing screws using the six new screws
evenly and tighten them to a torque setting of 0.5Nm.
v Test the unit functions correctly.
6.6.20 Fuses
6.6.20.1 All the table fuses are detailed in the Technical
Data Section 2.5.5. When replacing fuses check for any
obvious causes and investigate the reason for failure if
the fuse continues to fail.
6.6.20.2 To access fuses inside the covers, remove and
replace the covers as detailed in section 6.2.
6.6.21 Table infrared, code change
6.6.21.1 It is possible to reprogram the identifier code
of the table to match that of any handset, using a
combination of button presses, proceed as follows:-
i Press and hold button B16 of Fig. 6.10.
ii Whilst continuing to hold button B16 press and hold
button B17 of Fig. 6.10. There must be a short gap
between these button presses and do not try to push
them together or in the reverse sequence as this
will not work.
iii Continue to hold both buttons B16 and B17 until the
hand control LED (item 22, Fig 1.0) comes ‘on’ and
then release the buttons. The LED will stay on for 2
seconds to indicate that the table identifier code now
matches the handset. Test that the table responds
correctly to the handset.
iv Write the new identifier code (i.e. the infrared
handset identifier code) on the serial label of the
table in the space provided (see Fig. 6.9) deleting
the original one.
6.6.22 Infrared handset, code change
6.6.22.1 It is possible to change the identifier code of
the infrared handset to match that of any table, obtain
Service Kit Part No. 111040 or 111745 (see ‘Note’ in section
6.6.19.2) and proceed as follows:-
i Follow 6.6.19.2 (i) to gain access to the handset
PCA.
ii Locate on the PCA the two switches controlling the
infrared code. These should be set to match the
code on the units label, see Fig. 6.9.
iii Using a slot head screwdriver of a suitable size
rotate the switches to the required new control code
(note each switch can be set to a hexadecimal
setting of 0-F). Switch 1 is the first part of the two
digit code.
iv Amend the label on the handset to reflect the new
setting as clearly as possible in the space provided
and delete the old code.
v Check all connections and reassemble the handset
using the new screws and tighten them to a torque
setting of 0.5Nm as detailed in 6.6.19.2 (iii-v) noting
that the new seal is required to maintain the IP rating.
Test that the table responds correctly to the re-coded
handset.
