Table 7-1: SDMS40 mounting procedure
Step Procedure
1
Attach the L-shaped mount to the flat back mount using the common hole and cres-
cent shaped screw holes.
2 Using FIGURE 7-2 (p. 7), decide which angle your sensor is to be mounted at.
3
Bolt the L-shaped mounting piece to the underside of the sensor. The big middle
circle should line up with the cable connector.
4
Install sensor and mount 1 m above the maximum seasonal snow depth height. For
mounting to poles, use the provided hose clamps.
5
Line up the connector end of the cable to the cable connector on the sensor.
Lightly push the connector into place and screw the connector to secure.
7.1.1 Adjusting inclination angle or direction of the
SDMS40
The SDMS40 can be installed at any angle between 0 and 45 degrees from the pole. After loosely
tightening the screw on the common hole (
FIGURE 7-1 (p. 7)), the inclination angle can be
adjusted in 5 degree increments by matching one of the six holes on the flat backed mount
attached to the pole (
FIGURE 7-2 (p. 7)). Use the second screw to fix the inclination angle by
tightening the screw through the SDMS40 part and the bracket. Completely tighten the common
hole screw. See
FIGURE 7-2 (p. 7) for mounting angle options.
7.2 Wiring
The SDMS40 requires a 12 to 15 Vdc power supply capable of providing up to 2 A continuously.
Ensure the power is turned off before connecting the sensor.
CAUTION:
To avoid damage to the instrument, ensure that the power is turned off while wiring.
Align markers on the male and female connectors to plug in the cable to the sensor. The cable
comes with a 1-Position Terminal Connector attached to the blue wire and another 1-Position
Terminal Connector attached to the yellow wire (
FIGURE 7-3 (p. 9)).
