3. Set Calibration Enable to Enable.
4. Input a test output mA value. The controller will make
the ISM output this mA value upon exiting the menu us-
ing the back arrow key. See Table 16 for corresponding
mA and frequency signals. Note that in current software it
is necessary to execute “Dsable,” then “Enable” prior to
sending a different signal to the drive. Verify/calibrate
Target and Actual VFD speed at 70 to 100%. Have Rock-
well Start-up Engineer calibrate input to ISM 2M Aux to
close at Target Speed 58%.
5. If required, input the actual reading of mA value from
VFD or mA meter.
6. PIC 5 will calculate the calibration factor as follows:
Calibration Factor = 1000 * (Actual Reading mA –
Output mA)
Range: 0 to 2000
Table 16 — Corresponding mA and Frequency
Signals
NOTE: Parentheses indicate testing only with no motor running.
Calibrating J6 0-10V Input (from VFD)
1. When the chiller is running, record the VFD feedback
voltage and the actual reading on the ISM. Note that it is
possible that calibration is only required at the drive.
2. Shut down the chiller.
3. Go to Main Menu
Maintenance Menu
ISM
Calibration.
4. Select J6 0-10V Input. The ISM_CAL2 screen is dis-
5. Set Calibration Enable to Enable.
6. Input the VFD feedback voltage.
7. Input the actual ISM reading.
8. PIC 5 will calculate the calibration factor as follows:
Calibration Factor = 1000 * (VFD feedback voltage/
ISM actual reading voltage)
Range: 800 to 1200
9. Verify that the PIC control exits calibration mode.
ALARM EMAIL — The alarm email function sends auto-
matic email messages to specified service personnel for remote
maintenance purposes. This function can be set up from the
second page of Configuration Menu
E-Mail Configuration
(EMAILCFG). Subsequently if there is an alarm the function
will send an e-mail message. Another message is sent when all
alarms return to normal. See Fig. 43-45.
