2. Secure the rear section of the case to the wall or junction box using
the supplied screws, and make necessary wire connections.
3. Select Voltage or Current output option and Voltage range (0-10 V
or 0-5 V) using the SW1, switches #1 and #2 as shown on the
internal label (Figure 1 and Table 1).
Note:
SW1 controls both CO
simultaneously.
Factory default setting is Voltage outputs 0-10V.
