Current Sensor Module Crestron ST-CS
Threshold Adjustment
1. Attach the ST-CS power plug (labeled POWER IN) to a live AC outlet.
2. Connect the ST-CS to Cresnet; use ST-CNB, CNRJ11 or C2N-HBLOCK
(each sold separately).
3. If using the external power pack, attach the supplied power pack to the 12V
power connector (labeled 12 VDC .5A). If connecting to Cresnet, 24 VDC
is provided by the network.
4. Observe illumination of the PWR LED when power is supplied to the ST-
CS.
5. Observe illumination of the NET LED when communication to Cresnet is
established.
NOTE: If the NET LED is not illuminated, do not proceed. Refer to “Identity
Code” on page 7 and reassign the Net ID, if necessary. Ensure that a valid program
is loaded into the control system.
6. Rotate full load POT (labeled FULL) clockwise 3 to adjust the POT to
maximum range.
7. Rotate partial load POT (labeled PARTIAL) clockwise 3 to adjust the POT
to maximum range.
8. Attach the device power cord to the ST-CS power socket (labeled POWER
A).
9. Power on the device and observe illumination of the full load LED (labeled
FULL).
10. Slowly rotate the full load POT counterclockwise 4 until the full load LED
extinguishes and the partial load LED (labeled PARTIAL) illuminates.
11. Slowly rotate the full load POT clockwise 3 until the full load LED
illuminates again. The threshold has been determined.
12. Power off the device. And observe that the full load LED extinguishes and
the partial load LED illuminates.
13. Slowly rotate the partial load POT counterclockwise 4 until the partial
LED extinguishes.
14. Slowly rotate the partial load POT clockwise 3 until the partial load LED
illuminates again. The threshold has been determined.
