Automatic Calibration Option

Siemens Industry, Inc. Start-up Procedures 140-1342
Restricted 2015-11-09
1. Set FLO COEF to initial values that match your hardware configuration.
2. Work with a balancer to obtain the exact value(s) for FLO COEF using the following
formula to fine-tune the flow coefficient:
New Flow Coefficient = (Actual Volume ÷ Controller Volume) × Old Flow Coefficient
The actual volume is the value obtained from the balancer’s measurements. The
controller volume is the value obtained from EXH VOL. If the controller volume is not
within 5% of the actual volume, repeat the procedure until it is. Loose or kinked flow
sensor tubes, tubing connected backwards, and improper actuator and/or Damper
operation can cause inaccurate readings.
Automatic Calibration Option
This only functions when using the OAVS. To set CAL SETUP, select the automatic
calibration option that best meets the job’s requirements from the following table. It is
highly recommended that Option 4, the factory default mode, be used.
At the start of the calibration cycle, the controller automatically sets CAL AIR to YES.
When the cycle is complete, it sets CAL AIR to
NO.
NOTE:
The air velocity sensor should be calibrated at least once every 24 hours. Make sure
that the sensor has been calibrated before balancing takes place, as this will affect
the balancer’s results.
CAL SETUP Options.
CAL SETUP
Option Values
Description
0 Calibration occurs ONLY when CAL AIR is set to YES.
1 Calibration occurs with an occupied to unoccupied mode changeover.
4
(factory default
mode)
Calibration occurs on the time interval set in CAL TIMER.
Example:
If CAL TIMER = 12, then the calibration period is 12 hours. In this
option, actual calibration is subject to a time delay of up to 10 minutes to
prevent it from interfering with a response to fume hood flow change(s).
This is the recommended option when using a controller with an Autozero
Module.
Setting Blank Display
Set BLANK DSPLY to NO in order to display airflow readings at the ODP.
NOTE:
If BLANK DSPLY is set to YES, alarms will still display at the ODP.
