Option 8 – Analog Output/Relay Option

NOTE:

Option 8 only addresses the setup of the analog output section on the dual function circuit board.

Option 8 utilizes the KJN8924, a dual function circuit board mounted internally to the back plate of the indicator. It
provides a four relay output for setpoint process control and a 4 - 20mA or 0 - 10 VDC analog output which is
configured and trimmed for zero and span in similar fashion as the older option 2 analog output (KHD8924).
Besides its dual function capabilities, the board uses a 16-bit DAC.

Table 4-16 shows the Option 8 configuration.

Table 4-16. Option 8 Configuration Parameters

Refer to Section 4.12.3 on page 45 for individual serial command option parameters for Option 8.

Analog Output Option Wiring

Table 4-17 and Figure 4-12 show the analog output wiring.

Table 4-17. Analog Output Wiring

Ribbon Cable Connection

The ribbon cable is a sixteen conductor cable that connects the TTL control logic levels (inputs and outputs) on J11
of the CPU board KGR8924 to J1 on the analog/relay option board.

8.2 zR

Enter weight value for analog Zero using the numeric keys. The

TARE

key will store new

value, while the display responds with Enter.

8.3 FS

Use the same procedure as 8.2 to enter the analog Full Scale value.

8.4 Zr.A

Zero Trim, while measuring the analog output, use the

lb/kg CONV

and

PRINT

keys to

increase/decrease the zero value. Inc.dec function forces a test mode zero output. The

TARE

key stores the new value.

8.5 SP.A

Span Trim, same as 8.4 except a span test mode output is provided.
