1. Since the H5CN Timer is capable of reading the input data at
any time during normal operation, the set time can be
changed during powerapplication. This feature sets back the
output from the timer by temporarily setting the longer time or
quickens the outputby settingtheshortertime.Duringnormal
operation, the set time may be accidentally changed by
touchingathumbwheelswitch.Topreventthispossibility, use
the optional protective cover Y92A-48B.
2. When thesettime is allzeroes (e.g.,000.0sor00hrs 00min),
there will be a momentary control output upon power
application which can be used to check normal output. When
changing the set time during normal operation, pay special
attention not to alter the set value to this state.
3. When changingthesettimewhilepower is beingsupplied,an
inadequate push of the thumbwheel switches will display two
numbers in one digital display window, causing the operating
time to drift widely. Therefore, press the thumb-wheel
switches surely. Take particular care in the case when the
otherthreedigits areallzero,sincethe improper setting ofthe
fourth switch to create four zeroes will cause a momentary
output.
