Introduction:
Thank-you for your purchase of the SK75 monitored power sup-
ply! We are proud to be included as part of your assembly
process.
This document is an operations guide for the SK75. The SK75
can be outfitted to supply power for either brush or brushless
electric tools. The SK75 is also configured to monitor the tool
while it’s running. This feature can aid in the manufacturing
process by determining if a fastener has been installed properly
and also by counting the number of fasteners that have been
installed.
Before using the SK75, it is recommended that the user read this
manual thoroughly. If this unit is mishandled a fatal accident,
bodily injury, or damage to the SK75 may occur.
This manual is intended to be a general guide to the operations of
the SK75. If any additional questions or concerns arise, please
contact a CE Electronics representative.
Warnings:
Do not disassemble the unit for repair or modifi-
cations. There is a high electrical voltage inside
the unit that could cause electric shock.
Do not allow any type of liquid to come into
contact with any part of the unit.
Immediately discontinue use of the unit if
smoke, an abnormal odor, or an unusual sound
is detected coming from the unit.

Unit Overview (continued):
A five pin circular connector is located on the face
of the unit. This connector is used to supply
power to a tool and also to read signals back from
the tool.
Two selector switches are located above the tool
connector. The soft start switch turns the soft
start feature on and off. If the soft start feature
is enabled, the tool will spin slowly for a revo-
lution or two before jumping up to full speed.
Tool speed is governed by the speed switch.
When this switch is in the high setting, the
VDC out will be 30VDC. On the low setting, the power supply
provides 20VDC. The tool’s speed is directly proportional to out-
put voltage.
The rear panel on the unit
contains several items. The
main power switch for the
unit and the power entry
module are found on the
back panel. This unit is
capable of running on an
AC input voltage of 100VAC to 240VAC.
A keyswitch is provided on the unit’s back panel. The key switch
will allow a user to reach the programmable functions without
entering a password.
The unit’s beeper provides audible feedback when rejects occur
and can provide a double-beep when a batch accept occurs.
The RS-232 port can be used as a secondary means of program-
ming the unit or getting information from the unit.

Unit Overview
The user interface on the
SK75 is equipped with four
arrow buttons (up, down,
left and right) an enter but-
ton and an escape button.
These buttons are used dur-
ing programming.
The arrow keys are used to
navigate through menus,
raise and lower values dur-
ing programs, and move the
cursor to select items that
need to be edited.
The enter (ENT) button is typically used to select an item or save
a value once it has been edited. The escape (ESC) button is used
to abort an editing process without saving a new value
A two line by sixteen character
back-lit LCD display is part of the
user interface. This display will
provide the user with feedback dur-
ing the run mode and guide the user
through programming functions.
Above the LCD display, there are three status indicators. The
cycle status indicator will light up each time a fastening process is
completed successfully. The batch status indiction will be lit
when the final fastener is completed in a group. If a fastening
process is not completed properly, the reject status indicator will
illuminate.
The user interface on the SK75 can be mounted either in the face
of the unit or on the lid.

Unit Overview (continued) :
The 12 pin connector on the back of the
unit contains several input and output
functions.
A remote start feature can be accessed by
shorting together pins 1 and 2. The
remote start feature needs to be enabled
by turning on dip-switch 2 on the
CE3068X board inside the unit.
All of the inputs are optically isolated. In
order to use an input, an external power
supply ground must be placed on pin 3 (Opto-Common). Then
that supply’s same regulated 24VDC can be used to reset the unit
on pin 4 or select one of eight parameters on pins 5,6 and 7.
Several relay outputs are provided to notify external systems
when events occur. In order to use a relay, a regulated voltage
needs to be placed on pin 12, relay common. When an even
occurs, that voltage will be returned on the relay pin that is asso-
ciated with the event. For example, when the tool is running, the
voltage that is placed on pin 12 will be returned on pin 11.
Monitor Mode:
There are three screens associated with the monitor mode.
Pressing any of the arrow keys allows the user to change the view
on the LCD screen.
The first of these screens will
show the current parameter,
status of the last fastening, cur-
rent count and the number of
fasteners in the batch.
