8.5. SERIAL OUTPUT
Each Indicating transmitter has a serial output not used by the Divert Control unit. This serial output is select-
able RS-232/RS-485 (see PR-01-S Manual) and contains concentration, temperature and error data. It contains
also information whether the refractometer is in divert operation or not.
Possible uses of the Serial output: To communicate with a computer substituting the Divert Control unit.
8.6. CURRENT OUTPUT SIGNAL
Each Indicating transmitter provides a 4-20 mA output concentration signal not used by the Divert system. To
calibrate this signal for suitable %Solids range, press Calibrate/Output signal/Current output, see PR-01-S
Manual.
8.7. EXTERNAL DC POWER SUPPLY
The Divert Control unit may be connected to a DC power supply as a back-up. At AC power failure the refrac-
tometers will black-out, but the Divert Control unit will still work. In this case the DIVERT signal can be pre-
vented by turning the key to OVERRIDE. Terminals are 15 (+24VDC) and 16 (ground).
The power requirement is 24 VDC, 500 mA.
8.8. DIVERT CONTROL UNIT CARD IN THE REMOTE UNIT
In the remote unit the divert control card the third dip switch SW3 must be in the ON position (“up”).
See Figure 3.13 and Sections 5.2. and 5.7.
