In this case 119/92 drives the single-phase motor in both rotation senses; rotation sense is changed by inverting the starting
winding with respect to power winding.
Set up board 119/92 as shown in schematic diagram No. 1.
EXAMPLES OF HOW TO CONNECT THE CONTROL TERMINAL BOARD
Connection of 2-wire speed regulating potentiometer:
Should you need to use the 2-wire speed regulating potentiometer (as for instance
when replacing Rowan drives of previous manufacture such as old C119) close
microswitch S1 and connect a 10 KOhm potentiometer; speed regulation with 2-
wire potentiometer is not very linear with respect to its rotation.
Selection of different speeds with more potentiometers in parallel:
Two or more potentiometers can be connected in parallel making sure that the
overall resistance between terminals 4 and 6 is not lower than 3 KOhm.
Motor torque limitation through external potentiometer:
The potentiometer value has not to load the voltage reference of +10Vdc on terminal
4 (R= 3Kohm including the value of the potentiometer); in this case close microswitch
S2 and it is possible to limit the regulation range of the potentiometer by using
trimmer P1 (max.) and P2 (min.). If maximum torque internal limitation were enough,
the external potentiometer can be omitted: in this case close microswitch S1 and
limit torque by regulating trimmer P1.
Speed/torque control from analog signal 0/+10VDC:
In code 119/92 speed and torque regulations, in addition to the conventional
manual potentiometer, can be performed by applying a 0/+10 VDC signal; depending
on requirements, this signal can be picked up by Rowan interface boards of by other
commercial equipment as PLCs, LOGIC BOARDS, COMPUTERS, etc.; the
connection can be carried out directly because the board inputs are galvanically
insulated from high voltage. Input impedance is 100 KOhm. Close microswitch S2.

This is the basic schematic
diagram for drive 119/92
connection; the two individual
diagrams show how to manually
invert the rotation sense of the
motor by operating on power
connections (tachometer
dynamo polarity does not need
to be inverted); speed regulation
is by potentiometer connected
with 3 wires which ensures linear
regulation of speed with respect
to potentiometer rotation,
whereas torque adjustment is
excluded. In this case (if the motor
is a 4-pole one) only microswitch
S4 is to be closed.
