Introduction
Warner Electric’s CS-805-1 and CS-805-2
series clutch/brake controls are designed for
operation with Warner Electric electrically
released brakes. The correct brake release volt-
age is a specific point between 35-75VDC. This
point is set by adjusting the control at the time
of brake installation. These controls are factory
set for 60 volts output.
The CS-805-1 and CS-805-2 controls oper-
ate from 120/230VAC single phase input power.
Switching may be provided on either the AC or
DC side of the control.
The CS-805-1 and the CS-805-2 have an
internal adjustment potentiometer that is use for
the release band adjustment. The CS 805-2 is
similar to the CS-805-1 except that it has
torque adjustment capability for soft stop appli-
cations. The CS 805-2 requires two switching
circuits when used for those applications requir-
ing soft engagement.

Mounting
Any vertical, horizontal, or angled surface is suit-
able for mounting the CS-805-1 or CS-805-
2. Follow these procedures to mount your con-
trol:
a. Remove the front cover by removing the top
retaining screws.
b. Set the control on the mounting surface and
mark for the four mounting holes in accor-
dance with dimensions.
c. Install and tighten the four screws.
The control is now ready to be wired.
To avoid injury (or even death),
always make certain all power is off efore
attempting to install this control or any elec-
trical equipment. Do not touch the oard if
power is applied.

Installation
a. For 115VAC: Connect power supply to termi-
nals 1 and 4. Install a jumper between termi-
nal 1 and terminal 2. Also, install a second
jumper between terminal 3 and terminal 4.
For 230VAC: Connect power supply to termi-
nals 1 and 4. Install a jumper between termi-
nal 2 and terminal 3.
b. A chassis ground should be provided as a
non-current conducting ground wire (color
coded green). Connect this ground to termi-
nal 9.
c. Switching.
• For switching DC side: switch must be
connected to terminals 7 and 8. Switch
open will allow brake to be engaged.
Switch closed will release the brake. For
CS-805-2 Only: Switch open will allow
brake to be partially engaged and AC
power off will allow brake to be fully
engaged.
• For switching AC side: Line power off will
allow brake to be engaged. Line power on
will release brake. Install a jumper
between terminals 7 and 8.
d. Connect the positive terminal of the brake to
terminal 6 on the control and the negative
terminal of the brake to the terminal 5 on the
control.
Brake Release Adjustment
When setting the CS-805 control, the objec-
tive is to achieve armature release by adjusting
the coil voltage so it counteracts the permanent
magnet to the maximum extent possible.
Proceed as follows:
a. Turn on the control. Loosen locking nut on
the adjustment potentiometer. Turn the
potentiometer adjusting screw to the maxi-
mum counterclockwise position. Slowly turn
the adjustment screw clockwise until the
brake armature disengages from the magnet.
If the usual autogap spring is used, this will
normally cause the armature to separate
approximately 1/32" from the magnet. If the
autogap is not used, an external release force
of approximately 5-10 pounds should be
applied by hand, to detect the point of arma-
ture release. Using a voltmeter, note and
record the voltage at this point.
b. Turn the adjusting screw to the maximum
clockwise position that will normally cause
the armature to be reengaged. If the armature
does not make contact, it should be physi-
cally moved into contact, with caution exer-
cised to prevent fingers from being injured.
c. Turn the adjusting screw slowly counterclock-
wise until the armature releases through the
same technique as used under (a). Note and
record the voltage, which will be somewhat
higher than the value noted under (a). Adjust
the final voltage setting to the mid-point
between the two readings and tighten the
locking nut on the adjustment screw. The
brake is then ready for normal operation.
For CS-805-2 Only: Set partial engagement
torque the external potentiometer. Switch con-
nected to terminals 7 and 8 must be open to
make this adjustment. A setting of 10 gives
maximum torque.
