Designated use:
Electronic timers are used wherever a
procedure needs to be time-controlled.
AP 117 electronic timers are suitable
for timed activation of electric external
vibrators, solenoid valves and motor
overheating protection.
With these timers electric vibrators,
pneumatic vibrators, pneumatic im-
pactors and other drives can be
switched on and off exactly to the sec-
ond.
By selecting suitable pause times, the
operation of the vibrators is optimized,
drive energy can be saved and the
noise level lowered.
Any other usage is considered to be
improper.
The electronic timer has no safety de-
vices of its own.
