Terminology
Program per channel
Examples
- 1x24x2 is a daily timer (1x24); minimum duration
between 2 subsequent switchings (=shortest
switching time) is 30 minutes (x2).
- 7x24:3 is a weekly timer (7x24); minimum duration
between 2 subsequent switchings is 3 hours (:3).
- 1x24x4 & 7x24:12 is timer with a combined daily
and weekly program (1x24 and 7x24); minimum
duration between 2 subsequent switchings is 15
minutes for the daily dial (x4) and 2 hours for the
weekly dial (:12).
Manual override
During normal operation, the output contact of the
timer is operated according to the settings of the
dial-switches. However, at all time it is possible to
manually override this operation for each channel
individually.
The different overrides are as follows (see also photo 5):
- 1: always forces the output of that channel to the
on-status,
- 0: always forces the output of that channel to the
off-status.
Running reserve
The time during which a timer can continue to run
without being externally supplied with power is called
the running reserve. The 3, 4 and 6 module devices
have a running reserve of 150 hours, while due to
the limited space available, this is 50 hours for the
1 module electromechanical timer.
Programming
As is illustrated in photo 6, the programming of the
Classic timers is very easy: moving the dial-switches
outwards
1 , switches the output-contact to the on-
position when this switch passes the contact
2 ,
moving them inwards switches the output contact
to the off-position.
In case dials with plastic switches are to be used
- This range covers 1 and 2 channel devices, with
daily or/and weekly program, with or without
running reserve.
- The voltage-free change-over output contact is
capable of switching a resistive load of 16A/250V
and an inductive load of 4A/250V.
- The shortest switch-on time for the daily version
is 30 minutes and for the weekly version is
3 hours.
- The running reserve is 150 hours.
- The program is set by means of unlosable plastic
switches on a dial.
- Manual override is possible at all time by means of
a 0-clock-1-switch on the front of the device (for
the 1 module device at least a clock-1 switch
should be available).
- The electromechanical timers can be sealed in
order to avoid accidental or deliberate alteration of
time, date and program.
- All terminals have the safety-feature and have
captive Pozidriv screws.
- The devices are DIN-rail mountable.
- The electromechanical timers all have a circuit
indicator window, in order to easily identify their
function (i.e. heating, lighting, etc.).
