CS/CSP/MCS SERIES CURRENT SWITCHES
5
31-00432M—01
Honeywell’s Adjustable Turn-On ECM Current Switch
allows you to set/adjust your turn-on threshold
appropriately for your application. Set the dial so that the
turn-on amperage is slightly higher than your ECM stand-
by current. This will typically be around 400mA.
On startup, the sensor output will close when monitored
current exceeds dial setting, and open if monitored
current is below the dial setting minus the fixed hysterisis
value of the current switch.
CSP-NO-AECM SETUP
(RECOMMENDED)
Follow all safety precautions outlined in this manual.
Follow all requirements in NFPA 70E for safe work
practices and for Personal Protective Equipment (USA)
and other applicable local codes when installing this
product.
Read all warnings carefully.
Respectez toutes les précautions de sécurité décrites
dans ce manuel.
Respectez toutes les exigences de la norme NFPA 70E
concernant les pratiques de travail sécuritaires et les
équipements de protection individuelle (États-Unis), ainsi
que les autres codes locaux applicables lors de
l’installation de ce produit.
Lisez attentivement tous les avertissements.
1.
With ECM powered on but not running measure the
ECM current draw with a meter capable of measur-
ing current.
2.
Turn power off to ECM and set dial on current sensor
to a value slightly higher than what you measured in
step 1. Example, measurement of 500mA from
meter, set dial to about 600mA.
3.
Power on ECM and verify OPEN LED is on.
4.
Next, run ECM at minimum speed and verify
CLOSED LED is on.
5.
Stop ECM but leave powered on and verify OPEN
LED is on.
6.
Setup is now complete. You may need to repeat steps
1 through 5 above during initial setup to get correct
setting. Once adjusted the Honeywell ECM current
switch will provide a true status output as shown in
the chart above.
CSP-NO-AECM SETUP
(ALTERNATE)

1.
Dial is set from the factory to a value of about
500mA.
2.
Once installed on the ECM conductor with your
motor STOPPED but powered on, verify the OPEN
LED is on. If OPEN LED is off adjust dial clockwise
until OPEN LED is on.
3.
Turn dial counter clockwise until CLOSED LED is on.
This is the turn-on amperage or approximate value
of your ECM stand-by current.
4.
Turn dial clockwise until CLOSED LED is off and
continue clockwise slightly to give a margin of oper-
ation between the on and off states. Leave dial at
this setting and you’re done with the current sensor
setup.

CALIBRATION/TRAINING
No calibration is necessary.
Sensor will automatically detect belt loss on motors
operated by variable speed drive after 10 seconds of
operation above 40Hz. This is because the device leaves
the factory in the 40Hz training mode.
OPTIONAL MANUAL SETUP: To reset and restart
calibration/training, press/hold button for 1 second(40Hz
mode) or 3 seconds (50Hz mode). LED will make 4 blinks
in 5 seconds which indicates the device is in “Training”
mode. Operate motor above 40Hz for 10 seconds (40Hz
mode) or 50Hz for 10 seconds (50Hz mode), recommend
45Hz and 55Hz respectively.
To activate go/no mode, press/hold button for 5 seconds.
LED will make 3 fast blinks.
