MA
Continuous cycling timer - fast cycle-end after voltage off and
cycle resumed at slow constant speed
MA
When MA closes, R1, R2 & R3 change over - there is supply to ML so
P1 changes over.
Voltage off - R1, R2 & R3 change over
Voltage back on - MR is supplied via P1 and P2 - when P1 changes
over, there is supply to ML
Single-cycle timer, halt in intermediate position, fast cycle-end
after voltage off and cycle resumed at slow speed
Same operation as in example 3 - ML turns until P2 changes over.
There are other possible layouts, please consult us.
Important note :
These circuits require one or more control circuits (P1, P2). In your
order, be sure to state the total number of control circuits used.
Reducing the minimum opening or closing time of
contacts
A single minimum time which is too short during a program may
sometimes prevent a timer from being used. A special circuit allows
this problem to be overcome.
Example :
The minimum time normally obtainable with a standard cut-out is
1/60th of the total duration of the cycle, i.e. 1 second.

Closure of a contact
Circuit : a second contact, connected in series with the first, closes
out of synchronisation with the first. There is only a supply to the
load circuit while both contacts are closed.
Opening of a contact
These circuits, which can be used with all timers, allow the minimum
time interval to be reduced by approximately half.
N.B. : These two circuits can only be obtained with adjustable cams.
