Important
Although every care is taken to ensure the accuracy of the electrical circuit diagrams shown, SANGAMO
or associated companies cannot be held responsible or liable for circuit connections other than those directly
associated with the S250 & Q550 ranges of time switches. As the control mechanism is similar to that
used in an ordinary quartz clock, there will be a perceptual ticking.
Due to the variety of loads, environment and applications, the battery is built into the circuit of the printed
circuit board and, therefore, the timeswitch will cease to operate or run slow after its expectancy life of
10 years (dependant on the environment).
A battery replacement kit for fitting by a suitably qualified person is available by contacting our customer
services department.
