Fig. 6. Wiring for Potentiometer Control
For controlling up to six Series 90s in parallel with a 135 ohm
pot or Series 90 controller, add the appropriate resistor
indicated in the table below to ONE of the Series 90 motors,
from terminal B to terminal W. As an alternative, one
221508A2 module can be used to provide any of the resistor
values given below:

USE NEC CLASS 1 WIRING UNLESS POWER SUPPLY
MEETS CLASS 2 REQUIREMENTS. TAPE UNUSED LEADS.
ENSURE THE CURRENT DRAW OF THE EXTERNAL CIRCUIT
IS LESS THAN SWITCH CONTACT RATING.
ON TWO-SWITCH MOTORS, SECOND SWITCH HAS BLACK
LEADS WITH BLUE, YELLOW, AND RED TRACERS.
SOME AUXILIARY SWITCH ASSEMBLIES INCLUDE ONLY
RED AND YELLOW LEADS. SOME OTHERS DO NOT INCLUDE
THE YELLOW LEAD.
