The Danaher family of actuator controls - a choice of separate or combined power supplies and controls to meet
your various needs.
MCS-2015
A power supply for use with a remote control station,
photoscanner or programmable controller to run any 24
VDC actuator. 115/230 VAC input, 24 VDC output, thermal
overload protection, fused, power on/off switch.
MCS-2025
Combines the power supply of the MCS-2015 and the
control of the PC compatible MCS 2020 in a single
enclosure for ease of installation and wiring.
MCS-2020
A control that can be used with the MCS-2015 or other 12
or 24 VDC power sources. Provides extend, retract, jog,
run and auto return functions. Programmable controller
compatible, 12 or 24 VDC input-output.
MCS-2035
Combines the power supply of the MCS-2015 and the
control of the PC compatible MCS-2030 in one enclosure
for ease of installation and wiring.
MCS-2030
Same as the MCS-2020 but includes an analog meter to
display the position feedback from the Electrak 100.

Application Notes
I. Always make sure power is off before attempting to work on or near the actuator and its electrical controls.
2. Electrak 10 actuators are load protected with a slip clutch. The clutch will slip when the load exceeds the
actuator’s rating, preventing any movement of the load. The clutch is factory set based on load rating.
3. The duty cycle for the Electrak 10 actuator is 25% “on time”. For instance, an actuator operating for 25 seconds
must remain off for 75 seconds before operating again. Exceeding this maximum will cause the motor to overheat
and trip its internal thermal breaker.
4. Electrak 10 actuators are weather protected for use in outdoor applications, but they are not waterproof and
should not be used in underwater conditions
5. Electrak 10 actuators are not explosion or dust ignition proof; do not use in those types of environments.
6. Electrak 10 actuators are factory lubricated for life. No disassembly is ever required for routine maintenance
purposes.

MOUNTING
Danaher linear actuators are quickly and easily mounted
by slipping pins through the holes on each end of the unit
and into brackets on the machine frame and the load.
Half inch diameter solid pins provide maximum holding
strength and a retaining or cotter pin on each end will
prevent the solid pin from falling out of its mounting
bracket. Roll or spring type mounting pins should be
avoided. The mounting pins must be parallel to each
other as shown in Figure 1. Pins which are not parallel to
each other may cause the actuator to bind.
The load should act along the stroke axis of the actuator
since off center loads may cause binding and lead to
premature failure. See Figure 2.
The actuator mounting brackets must be able to
withstand the torque which is developed when the unit
extends or retracts. Restraining torque required varies
with the model being used. See Figure 3 and the chart
below.
Make sure mounting pins are supported on both ends.
Cantilever mounts are unacceptable. Failure to do so
could shorten the life of the actuator.
NOTE: Do not attempt to mount the Electrak 10 on its cover tube. The tube is not designed to support the
forces required for this type of mounting.

Wiring
Danaher linear actuators should be connected in
accordance with the diagram show below.
Make sure power is off before attempting to wire
actuator.
WIRE GAUGE SELECTION
DC Actuators
Long lead wires between the power source and the
actuator will result in a voltage drop for DC units.
This voltage drop can be avoided by sizing the wires
in accordance with the following wire gauge selection
chart, which is based on a 12 or 24 VDC power source.
In order to use the chart, find the point of intersection of
the two known factors, such as amperage and distance,
and read the required wire gauge from the curves on the
chart. Example: A D12-2OB5 actuator draws 14 amps
current at rated load. The intersection of the maximum
current and the distance between the actuator and
power source (44 feet, for example) indicates the wire
gauge required (#12).
SWITCHES
Actuator direction (forward, reverse) is controlled with a
double-throw switch with the center position 11 off.”
DC Actuator Switches
DC actuators require double pole, double throw
switches. McGill switch no. 0111-004, Cutler Hammer
switch no. 8835- or equivalent are recommended and
are usually available locally. The required switch can be
purchased locally or from Danaher under part number
830-8004-016. Here are the required parameters:
- Double-pole, double-throw
- 20 Amp at 28 VDC
- Lever seal to keep out dirt and moisture
- Center “off”
- Two momentary contacts
- 15/32” bushing
- Screw terminals
CONNECTORS
Packard Electric connector 56 Series No. 2984883 and
56 Series No. 29692987. Male blade provided on DC
actuators.
ACTUATION
To extend actuator, connect red to positive and yellow to
negative. To retract actuator, connect yellow to positive
and red to negative.
ELECTRICAL INSTALLATION

Danaher actuators may also be interfaced with the MCS-2000 Series controller.
Available controllers are as follows:
MCS-2015 Power Supply - 110 VAC in, 24 VDC out, 17 Amp maximum.
MCS-2020 Actuator Controller - Capable of extend and retract functions in a jog or continuous run
model. For use with 12 or 24 VDC actuators.
MCS-2025 Combined Controller and 24 VDC power supply. Performs same functions as MCS-2020.

TROUBLESHOOTING
Covers D12 and D24 Models
General: The chart below will be helpful for isolating malfunctions in the control system, countering difficulties with
system start-up, and in troubleshooting for worn or broken mechanical or electrical components in units which have
been operating for sometime. For correct diagnosis it is important to do all tests before disassembling the actuator.
If the actuator is being used in conjunction with an MCS controller, see Troubleshooting Guide in controller manual
for additional checkpoints.
Symptom: Actuator will not extend/retract
Checkpoint Probable Cause Possible Solution
No voltage or amp draw Actuator not receiving power -Check power supply
Proper voltage, no amp draw Dead motor -Replace motor
Thermal overload cut-out -Let cool, check duty cycle
(when overheated)
Proper voltage, amp draw Actuator overloaded -Check rated load
present, clutch slips
Clutch worn too low -Replace clutch
(Excessive ratcheting)
Symptom: Actuator stops in mid-stroke
Checkpoint Probable Cause Possible Solution
Clutch slips Actuator overloaded -Check rated load
Clutch doesn’t slip, no amps Blown fuse (customer provided) -Replace fuse
Thermal cut-out -Let cool, check duty cycle
Clutch doesn’t slip, amps Motor stalled -Check voltage too low
present
If the above checks do not reveal the source of the difficulty, remove actuator from the mechanism to run by itself.
Watch and listen for any changes in behavior.
