ZENO
®
-3200 USER MANUAL
Coastal Environmental Systems (206) 682-6048
Page 169
The ZENO
®
-3200 conserves power by turning on a switched voltage only
when a sensor is read.
In the event that more than one sensor can be powered by a single switched
voltage, the ZENO
®
-3200 turns on the switched voltage as long as at least
one sensor requires power.
Line Item #6 is used to assign one of the five switched voltages in the Sensor Menu. The following table
below indicates the maximum current available from each source.
Line Item #6
Value
Power source Maximum current
0 No Switched Voltage 0
1 5 V Switched A 200 mA mean, 600 mA peak*
2 5 V Switched B 200 mA mean, 600 mA peak*
3 12 V Switched A 700 mA
4 12 V Switched B 150 mA
5 12 V Switched C 150 mA
*The two 5V switched power outputs can together provide a total of 200 mA mean power, 600 mA peak
power, partitioned as required
Connect the sensor's positive power terminal to the same switched voltage
on the ZENO

as specified in the ZENOSOFT
®
configuration.
Connect the sensor's negative power terminal (may also be called common
or return) to one of the grounds marked as GND on the ZENO
®
-3200 Front
Panel.

Refer to Section 13.2 for a full discussion on grounding.
10.3.11. Specifying Warm-up Time for a Sensor Using Switched Voltage
Your sensor may require time to warm up prior to being read in order to provide accurate measurements.
The ZENO
®
-3200 allows you to specify a Sensor Warm-up Time using Line Item #9 in the Sensor Menu
if your sensor is being powered by a switched voltage specified in Line Item #6.
