ADDITIONAL FEATURES
Special Relays for Non-Reversing and Reversing Multispeed Starters
General
Standard starters are not equipped with any special relays to require starting
at lowest speed, progressive acceleration or deceleration through each
speed, etc. However, when the type of motor or characteristics of the load
involved make certain starting or control sequences necessary, four types of
relays/timers are available to accomplish the required function.
Form R1 Compelling Relay
This relay makes it necessary for the motor to be started at low speed before
any higher speed can be selected. Pressing any push button except the low
speed will not start the motor. This arrangement insures that the motor will
always start the load at low speed. The stop button must be pressed before
it is possible to change from a higher to a lower speed.
Form R2 Accelerating Relay/Timer
When the starter is equipped with Form R2 accelerating relays, the ultimate
speed is determined by the button which is pressed, but the starter will start
the motor at low speed and then automatically accelerate it through
successive steps until the selected speed is reached. Definite time intervals
must elapse between each speed change. Individual timing relays are
provided for each interval, and all are adjustable. The stop button must be
pressed before it is possible to change from a higher to a lower speed.
Form R3 Decelerating Relay/Timer
This is similar in action to Form R2 accelerating relays, except that they
function to prevent immediate transfer from a higher to a lower speed. A
definite time interval, preset on the timer, must elapse between each speed
change.
Form R10 Antiplugging Relays/Timers
If it is necessary to have an imposed time delay when transferring from the
forward to the reverse direction or reverse to forward, then Form R10 should
be included in the form designation of the reversing multispeed starters.
This provides up to a 60 second delay in the transfer of the direction of the
motor, and can help prevent damage which could result from plugging.
