MFA 4p Wiring for Automatic Start Delay
Interlocks and Safety Pull Switches are not shown.
If
is initiated by programmable logic controller, closure time may be too brief to
allow MFA 4p contact to latch. In this case, program a timer contact into the circuit.
CSA requires an 8 A or less fuse to protect contacts. For 240 V AC, protect the contacts
with a 1 500 VA transformer as well.
Should the
feature on start-up not be required, power should be applied
continuously from a separate source and the potentiometer turned to zero. This is usually
necessary for automatic up-stream startup of conveying devices after the down-stream drive
has reached its operation speed.
