P1
By maintained contact
The cam profile will determine the number of steps as shown in dia-
gram 3.
Bi = two-position actuating contact
MP = timer motor
P1, P2 etc. = timer contacts
1st changeover of Bi = advance by one step, P1 changes over
2nd changeover of Bi = advance by one step, P1 changes over
Changeover time of Bi = > 1 step
Intermittent advance controlled by external time-base
MT = Time-base motor
MP = Timer motor
Continuous rotation in both directions
Continuous rotation in forward or reverse
Example :
Program which follows a step by step rise and return cycle (symmetrical)
in one direction and a continuous return in the other, etc.
Continuous single-cycle rotation in forward or reverse direction
Example :
Successive start-up of pumps or compressors with shutdown in rever-
se order. Start position can be returned to in course of rotation.
Inv. - Direction changer
MP = Reversible motor 82 470
C = Timer capacitor
P1, P2 = Timer contacts

Two speeds of rotation
As in the case of the basic units, the low-speed motor can be connected
for:
- continuous cycling
- single cycles
- stepping action.
The presence of the high-speed motor increases the options available
by allowing:
- automatic or controlled fast cycle-end
- reset to origin after power failure
- two-speed stepping action
- two-speed continuous cycling.
Controlled fast cycle-end with halt at origin
ML = low-speed motor
MR = high-speed motor
M.A. to M = motor ML turns
M.A. to A = motor MR fed from P1, fast reset to origin
Single-cycle timer - fast cycle-end after voltage off or
deliberate halt
R = relay coil
R1, R2, R3 = relay contacts
ARS = Safety stop-switch
IMP = Start
ML = Low-speed motor
MR = High-speed motor
P1, P2, etc.= Timer contacts
Pulse from IMP - R provides own supply via R1, P1
ML switched on by R2, supply to P3, P4 via R3
Changeover of P1 = End of cycle Voltage off; R1, R2 and R3 change
over
Voltage comes back on - supply to MR via P1 and P2; when P1
changes over, supply fed to ML
