CSM1 Threshold Adjustments
a. First, make sure the 3.5mm mini-plug is plugged into the appropriate sense jack on the
CBCSM1 and that it is powered ON via a 781RG Power Supply (not included). (The CSM1
gets low-voltage DC power from the CBCSM1 – not from the AC line.)
b. Select the correct position of the RANGE slider switch – the HI position is for devices with a
high current draw when ON, the LO position is for devices with a low current draw when ON
(based upon the lowest current draw state of the component when ON).
c. Manually turn the component ON.
d. Using a small (1/8” wide) blade screwdriver, rotate the current control to the full CLOCKWISE
position (LO CURRENT).
e. Rotate the control COUNTER-CLOCKWISE (towards the HI CURRENT position) until the
Threshold Adjustment LED goes OFF (Make ‘note’ of this position).
f. Turn the component OFF manually.
g. Rotate the control CLOCKWISE until the Threshold Adjustment just goes ON.
h. Set the control to a point midway between this and the setting in step ‘e’ above. This should
be the correct setting.
NOTE 1:
If you have trouble with the threshold adjustment correctly detecting the ON and OFF
states of the component, try changing the RANGE slider to the opposite position and then try the
adjustment again.
NOTE 2:
If the Threshold Adjustment LED does not go ON and OFF with the component power,
make minor adjustments to the threshold adjust until the LED is in proper sync.
