Analog Output Card Installation
PNs 67602 and 103138
Use the following procedure to install analog output cards in 820i and 920i indicators:
1. Disconnect indicator from power source.
WARNING
Disconnect power before removing indicator backplate.
2. Place indicator face-down on an anti-static work mat. Remove screws that hold the backplate to the
enclosure body.
CAUTION
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when
working inside the indicator enclosure.
3. Carefully align the large connector on the bottom side of the option card with the indicator option card slot
(J5 or J6 on the 920i, J6 on the 820i.). Press down to seat the option card in the CPU board connector.

4. Use the screws and lock washers provided in the option kit to secure the other end of the option card to the
threaded standoffs on the CPU board (see Figure 1).
5. Make connections to the option card as required. Use cable ties to secure loose cables inside the enclosure.
6. Set the mode selection jumper (see Figure 2) for voltage or current output.
7. Once cabling is complete, position the backplate over the enclosure and reinstall the backplate screws. Use
the torque pattern shown in the indicator Installation Manual to prevent distorting the backplate gasket.
Torque screws to 15 in-lb (1.7 N-m).
8. Ensure no excess cable is left inside the enclosure and tighten cord grips.
9. Reconnect power to the indicator.
10. Configure the analog output card as described on page 3.

Figure 2. Analog Output Cards
The indicator automatically recognizes all installed option cards when the unit is powered on. No
hardware-specific configuration is required to identify the newly-installed card to the system.
For the 820i, a single-channel analog output card is assigned as ALGOUT2; a dual-channel card is assigned
ALGOUT2 and ALGOUT4.
For the 920i, the single-channel card is assigned ALGOUTn, where nis the slot number (connector J5=slot 1,
J6=slot 2). Dual-channel cards use the same assignment for channel 1; channel 2 is assigned ALGOUTn+14. See
Table 1.

Slot 3 (expansion board) of a 880 is assigned as ALGOUT17.

2.2 Analog Output Calibration
The following calibration procedure requires a multimeter to measure voltage or current output from the analog
output module.
Note
The analog output must be calibrated after the indicator itself has been configured and calibrated.
1. Enter setup mode and go to the ALGOUT menu (see Figure 3):
• Set SOURCE1 for the number of the scale channel used as the source for the analog output
• Set MODE1 to track either gross or net weight from that scale
• Set OFFSET to 0% for 0–10 V or 0–20 mAoutput; set to 20% for 4–20 mA output
• Set ERRACT to specify how the analog output will respond to system error conditions
• Set MIN to lowest weight value to be tracked by the analog output
• Set MAX to highest weight value to be tracked by the analog output
•Forthe880 and 820i, MIN NEG and MAX NEG parameters allow tracking of negative weight values.
• MIN NEG - set to on to specify the minimum weight (MIN parameter) is a negative value.
• MAX NEG - set to on to specify the maximum weight (MAX parameter) is a negative value.

2. Connect multimeter to connector J1 on the analog output card:
• For voltage output, connect voltmeter leads to pins 3 and 4
• For current output, connect ammeter leads to pins 1 and 2
3. Adjust zero calibration: Scroll to the TWZERO parameter. Press to view zero value, then check voltage
or current reading on multimeter. Use the numeric keypad to adjust the zero value up or down.
4. Adjust span calibration: Scroll to the TWSPAN parameter. Press to view span value, then check voltage
or current reading on multimeter. Use the numeric keypad to adjust the span value up or down.
5. Final zero calibration: Return to the TWZERO parameter and verify that the zero calibration has not
drifted. Use the numeric keypad to adjust the zero value as required.
6. Return to normal mode. Analog output function can be verified using test weights.

For dual-channel cards, repeat calibration steps for the second (J2) connector.
See the 920i Installation Manual (PN 67887) or 820i Installation Manual (PN 93018) for more configuration
information.
Important
Connection to PLC Analog Input Module
If the PLC analog input uses a common ground (negative input of the analog card) and both PLC
channels are connected to the same option card, there is crosstalk and the values of the 2 inputs will be
merged.
Example: If one is inputting 6 mA and the other is inputting 12 mA they will merge and each looks like it is
inputting 9 mA.
6 + 12 / 2 = 9 mA
To prevent this cross talk, the PLC must have isolated grounds on the input channels.
