FITTING AUXILIARY SWITCHES - KIT 831-1-211

WARNING -
AUXILIARY SWITCHES MAY BE AT MAINS POTENTIAL.

Note: When used with the ALE actuator, fit auxiliary switch kit AFTER
carrying out stroke setting procedure. See 'Commissioning'.

1.

Remove cover.

2.

Undo fixing screw of main terminal block bracket 'A' and reposition
adjacent to conduit entry (Fig.4). Use the locating hole to position
bracket and tighten fixing screw. (Not applicable to ALE).

3.

Push the switch operating rod 'C' into the large hole in the base of
the actuator case (see Fig.5) until it clicks into the anti-rotation
bracket (G above).

4.

Fit auxiliary switch kit bracket 'B' in original position of main
terminals, adjacent to vertical switch operating rod 'C' (Fig.5). Use
the locating holes provided and tighten fixing screws.

5.

Note that micro-switches are adjustable, one (S1, S2 & S3) between
actuator positions 0 and 5, the other (S4, S5 & S6) between
positions 5 and 10.

6.

To adjust the switches, energise actuator (if commissioning in
progress) at correct voltage and run to position at which one switch
is required to operate. Alternatively, use manual operator facility.

7.

Loosen micro-switch fixing screws 'D' and slide assembly with
terminal block to point at which vertical operating rod 'C' just
operates switch (Fig.6). Hold assembly in this position and re-tighten
fixing screws.

8.

Now energise actuator, or use manual operator, to run actuator in
opposite direction to position at which second switch is required to
operate, then repeat the setting procedure, as items 5 & 6.

9.

Connect cables in accordance with system wiring diagram. Ensure
that all wiring is kept clear of internal moving parts. Replace cover.
