3.3.3 Analog Inputs
The Analog Inputs screen allows you to calibrate all the available analog inputs, such as a
sensor, a remote signal, or feedback from a device such as a valve. If reliable feedback or
external instrumentation indicates the reading is inaccurate, you can adjust its reading via the
Offset parameter. This process can be repeated for all available analog inputs.
Figure 3.3.3: Input/Output: Analog Inputs Screen
1. Go to: Main Menu → Calibration → Input/Output → Analog Inputs.
2. Press the Analog Name field and choose the sensor you want to view. The selected input
is displayed along with its current reading. The available Analog Inputs are:
• CO/Analog In
• Air Pump
• Spare Analog In 3
• Spare Analog In 2
• Flow
• Remote Analog In
• Spare Analog In 1
• Cas Vlv Fdbk (Cascade Valve Feedback)
3. If you chose Remote Analog In or Spare Analog In 1, 2 or 3 in step 2, the Function
parameter appears with a read-only display of the function to which the input is currently
assigned (assignments are made in Section 6.5.4: Analog Inputs):
• DHW Setpoint
• Swing V1 Feedback
• Swing V2 Feedback
• Blr VSP Feedback
• DHW VSP Fdbk
• SmartPlate VP
• NOx
• Other Setpoint
4. This screen includes the following additional parameters:
• Board Reference: Displays how the input connects to the Edge Controller, either
through the unit’s wiring harness or to specific pins on the unit’s I/O Board (see the I/O
board map in Section 2.11 of the Benchmark Platinum-Edge Installation Manual, OMM-
0136, GF-210).
• Offset: If necessary, you can adjust the Current Reading to match a reliable reading
or instrument by entering a value in this parameter. (Range: -2.0 to +2.0, default = 0.0)
• Current Reading: A read-only display of the current value. If no input is sensed, it
displays either INVALID or --- (blank).
5. You can repeat Steps 2 through 4 with the other Analog Inputs, as needed.
