Make sure that the wallbox is earthed if it is metal. Ensure that all
three terminals are tight before screwing the two plate fixing screws
supplied home sufficiently to locate the DS2 securely to the wall box.
Turn ON the mains supply.
If further DS2’s are required to control the same load they must
have all corresponding terminals wired in parallel with these
on the first DS2.
3. Commissioning.
Press the push button and the light(s)/appliance(s) under control
should come ON for approximately 3 seconds. During this time the
neon behind the push button switches off. If the load under control is
low energy or fluorescent lamps they will not switch ON immediately
and the light intensity may be reduced initially.
Having established that the DS2 is working correctly the mains supply
should be turned OFF and the two fixing screws removed from the
unit. The DS2 can then be pulled away from the wall to enable access
to the delay time adjuster and 2 gang range switch (see fig 2). The
delay time can then be set to the required level by setting the 2 gang
range switch according to table 1 and then adjusting the delay time
adjuster. The DS2 can then be fixed to the wall again using the two
fixing screws. The push in screw covers can now be fitted if required.
The mains supply should be turned ON and the push button pressed
to ensure the delay time is correct.
All delay times accurate to ±25%. Black – switch lever.
