CM Series Timers
These recycling timers repeat a continuous, adjustable on/off electrical cycle. They feature a heavy duty, synchronous motor mechanically connected to the camshaft through a unique gear and rack arrangement which allows 50 different speeds from each of the 12 available motor speeds. All load switches are single pole, double throw. The CM model features a single switch and is designed for base mounting.
Note  This timer requires a gear rack.
See below for gear rack specifications.

MC Series Timers
These recycling timers repeat a continuous, adjustable on/off electrical cycle. They feature a heavy duty, synchronous motor mechanically connected to the camshaft through a unique gear and rack arrangement which allows 50 different speeds from each of the 12 available motor speeds. All load switches are single pole, double throw. The MC series is available with 2 to 20 cams and switches. The MCE offers the same features as the MC plus a shaft extension on the bracket end. The adjustable split cams are calibrated in percentage for quick, accurate adjustment. All units are designed for base mounting and units with 9 or more switches are supplied with a heavy gauge aluminum base for added strength. Certain combinations of multiple switches and fast time cycles may require a special high torque motor.
Note  This timer requires a gear rack.

RC Series Timers
These cam timers are designed to accept a pulse from an outside source and complete exactly one revolutin following the pulse. A patented solenoid camandmotorcontrolswitch combination provides the single cycle action. The RC series features from 1 to 20 load cams and switches. All units feature a heavy duty synchronous motor mechanically connected to the cam shaft through a unique gear and rack arrangement which allows 50 different speeds from each of the 12 available motor speeds. The adjustable split cams are calibrated in percentage for quick, accurate adjustment. All units are desinged for base mounting and RC units with 8 or more independent load switches are supplied with a heavy gauge aluminum base for added strength. Certain combinations of multiple switches and fast time cycles may require a special high torque motor.
Note  This timer requires a gear rack.

Because of the increased torque encountered with multiswitch cam timers in the rapid time cycles, the Series MC0 and RC0 timers require High Torque Motors (HTM). This is also true of some MC1 and RC1 timers. (See vertical shaded area of chart.)
To determine the need of an HTM in the Series MC1 and RC1, multiply required time cycle in seconds by 2/3. The answer will be the maximum number of switches that can be operated with a standard timing motor; e.g. time cycle 15 seconds, 2/3 x 15s=10. 10 switches can be operated at 15 seconds with a standard timing motor, more than 10 load switches will require the use of an HTM.
If there is any doubt relative to the use of an HTM, consult factory. Note that the C12 Gear Rack (horizontal shaded area of the chart) provides a cam rotation speed directly proportional to the motor output; e.g. MC6=1 revolution in 5 minutes. Also, the letter C which signifies CYCLES = 1/60th of a second.
