1 GENERAL
This instruction manual contains important information
regarding the installation, operation, and troubleshooting
of the Metso V-Series Additional Limit Switches. Please
read these instructions carefully and save them for future
reference.
1.1 Description
The V-Series additional limit switches option provides two
dry contacts and are fully adjustable to trip at any position
throughout the cycle of the actuator. Each switch is oper-
ated by a stainless steel cam that is mounted directly onto
the output drive shaft. Additional switches are often used
for position indication or to interlock other devices (such
as in sequencing operations).
The switches are single pole, double throw switches rated
for 1/3 HP, 11 amps @125/230VAC, CSA certified. Auxiliary
switch kit P/N VC099000 is universal to all standard
V-Series actuators. The kit provides“flying wiring leads”for
termination inside the enclosure using the supplied 6
position terminal block.
This option will fit all actuators with the letter “N” preced-
ing the voltage designator in the part number on the
product nameplate.
1.2 Operation
Additional switches provide dry contacts only. Power to
the switches, if required, must be supplied externally.
