plastic front cover of actuator.
Note: Always test rotation of the valve in manual position mode to ensure that the handle
does not interfere with the actuator mounting stud and mounting piece.
Manual Operation: Always disconnect power before operating by hand.
Note position of drive sleeve pointer to be returned to. Depress the gray button, “A”, on
the side to release the handle. The valve can now be operated manually.
Never manually operate when gears are engaged.

ESBE Type 92P - see fig. 8 and 92K2 actuators, see fig. 10 in separate sections.
Warning: Always turn off all electrical power before removing or servicing the actuator.
– The actuator is powered using a 24VAC transformer, 3VA minimum.
– Remove the four cover screws and lift the cover off the actuator.
– Remove one (or two) of the wiring knockouts and install one (or two) of the “conduit
fittings”. All wires must go through these fittings.
– Attach the “common” from the control (or transformer) to terminal “N”.
– Connect the control output for clockwise rotation to “Upper terminal L1”, and connect
the control output for counterclockwise rotation to “Lower terminal L1”.
Auxiliary Switch
– ESBE 91EM, 92EM, 92-2EM and 93EM actuators include one fully adjustable auxiliary
switch. The wiring should be connected as shown in fig. 5. To set the switching position,
turn the cam (see fig. 6).
Reinstall the cover and secure it, before turning on the power.
Adjusting the Degree of Rotation
– ESBE 90 series actuators do not
require adjustment when used with ESBE valves.
However if the actuator is used for an application that requires a different degree of rotation, the middle and lower cams can be adjusted to provide between 30° and 180° of
rotation. For access to the cams, the cam operating the auxiliary switch must be removed
(see fig. 7).
Always turn off all power before adjustments are made.
Test: Test the valve rotation to ensure the valve is allowed to fully open and
fully close. Rotations of 30° to 180° are possible via middle and lower cams for
applications that require them. For access, aux. switch cam must be removed.

Motor Speed and Signal Selection, Type 92P Only, for “Proportional” Signals
– With power turned off, follow instructions for removing the cover.
– The 92P is designed for operating signals of 0-5VDC, 1-5VDC, 0-10VDC, 2-10VDC,
0-20mA and 4-20mA signals. The factory default setting is 0-10VDC.
– Running speed for 90° rotation is factory set at 60s, but can be changed to 90s or
120s.
– If required, the motor speed and operating signal can be changed to different values,
as shown on the PCB card (see fig. 9).
Wiring, Type 92P Only
– Connect the 24V AC or DC power supply to terminals 1 and 2 (see fig. 8).
– Connect the control signal to terminal 3.

Direction of Rotation, Type 92P Only
– The 92P is factory set to rotate in the clockwise direction. To change the direction of rotation to Counter-clockwise, change the position
of the jumper as shown on the PCB card (see
fig. 9). Reinstall the cover and secure it,
before turning on the power.

3-wire 4-wire
ESBE Regulator Type 92K2 – a complete
unit for constant temperature regulating.
Handling
For the best control the sensor shall be
placed about 3’ (1 m) downstream from
the valve (see fig. 11). The sensor must be
carefully insulated from the ambient temperature.
Wiring
See fig. 10.
Adjusting
The function of the regulator 92K2 is
adjusted by two knobs:
Right hand knob for temperature setting
from 59 – 158° F (+ 15° C to + 70° C)
Left hand knob for selection of intervals
between control signals from 1 to 70 seconds. Normally 30 seconds is suitable but
depending on installation characteristics a
longer or shorter interval can be used.
Direction of rotation
The direction of rotation can be reversed
by changing the position of the two jumpers (fig. 12).
Note: The installation shall include an
approved means to disconnect the power.
