Field Calibration
WBPEEUI240766B0 4 - 9
The following steps field calibrate channel one for the low-level
voltage range of -100 to +100 millivolt. Change specification S4
and use these steps to configure high level, or resistance
inputs. Also S4 of FC 216 must be consistent with the type of
calibration being performed.
1. Locate the block address in the controller of FC 217.
2. Verify that the I/O expander bus dipshunts are in place to
allow ASI module bus communications.
3. On the ASI module, for each input channel, place the
jumpers as shown in Figure
3-3 .
4. Set S2 of FC 217 to the block address of the FC 215 which
references the ASI module.
5. Insert the ASI module into a powered slot. The green LED
will be solid indicating the module is linked to a FC 215 in the
configuration.
6. Allow the ASI module to warm up for at least 15 minutes.
7. Put the controller in execute mode.
8. Set FC 217 for the required specifications. After each cali-
bration command is issued by performing a tune operation,
monitor the calibration command status to determine if any
errors have occurred during the field calibration.
This example calibrates channel one on the ASI module which
is referenced by the FC 215 at block address 100. For low level
voltage, disable the desired channel by tuning these values
into the specifications.
a. Disable point (S1 = 1).
b. ASI module referenced by FC 215 at block address 100
(S2 = 100).
c. ASI module channel one (S3 = 1).
9. Verify that the low-level voltage source is connected to
channel one of the ASI module to be calibrated and the source
voltage is set to the full scale value (+100 millivolt).
NOTE: Each time the source voltage is changed, at least 15 seconds settling
time is required before the point field calibration takes place. If the source itself
has a measurable settling time, add this to the 15 second requirement.
