Integrated Temperature And Battery Sensor; Analog Polarity Override - DPS Telecom NetGuardian 216T User Manual

Fig. 2.12.2. Reference 1 and Reference 2 correspond to the minimum and maximum output values of your analog

2.12.1 Integrated Temperature and Battery Sensor

The integrated temperature and battery sensor allows the user to monitor surrounding temperature as well as the
unit's current draw. If you are using the temperature or battery sensor, you must dedicate an analog port to each
one (see user manual for connection information).
CAUTION: Abort ambient room temperature cooler than the NetGuardian unit temperature.
Temperature Sensor
1. In the Description field enter a description in the analog channel you are using for the integrated
temperature sensor and set it to 7.
2. Under the Unit column, click on the abbreviated units link (e.g VDC, RH, F, etc.) to convert the reference
units and the native units for that analog channel (see Figure 2.12.2).
3. In Reference 1 enter iF (internal Fahrenheit) in the box next to VDC (the space may already contain the
abbreviation VDC); see Figure 2.12.2. This enables the NetGuardian's pre-configured temperature settings.
Repeat this step for Reference 2 .
4. Set your desired thresholds (see Section 2.12 for instructions).
5. If you have connected the external temperature sensor, follow the above procedure to configure, except set it
to channel 8 and enter eF (external Fahrenheit) in the Reference menu.
Current Sensor
1. In the Description field enter a description in the analog channel you are using for the integrated current
sensor (5 for power feed A or 6 for power feed B).
2. Set your desired thresholds (see Section 2.12 for instructions). Be sure to set your thresholds in reference to
your NetGuardian's power input (e.g. –24 VDC, –48 VDC, or wide range).

2.12.2 Analog Polarity Override

iF : internal temperature sensor in fahrenheit or iC for celsius
oV+ : override polarity VDC to positive
oV- : override polarity VDC to negative
If you have a positive powered NetGuardian, you may want to use this feature if you are using the internal
battery sensor. The Web browser interface will override oV+ and oV- tags and show VDC. So you won't have to
view an uncommon looking tag while in monitor mode.
