6.3. DIAGNOSTIC MESSAGES
For diagnostic messages in the Indicating transmitter display, see the PR-01-S manual. The following mes-
sages appear only in divert systems:
- "In divert control operation" or "Removed from divert control", Section 2.6.
- "Solids warning" and "Solids alarm", Section 5.4.
- ** Divert control fault **
This message indicates that there is no communication to the divert control unit, probably cable error, Figure
3.12, cable 2.
If the instrument is not applied in a divert control system, de-activate the divert function, see end of Section
5.2.
Further the message ** Relay unit fault ** may appear. This indicates that the Relay unit PR-7080 functions
are defined, but no Relay unit is connected. Normally a Relay unit is not used in a Divert system because the
wash contacts are in the Divert control unit. Clear the relay functions by the key sequence Calibrate/Relay unit
and select an "0 Not Defined" for all four relays. For using an optional relay unit, see PR-01-S Manual, sec-
tion 9.1.
6.4. DIAGNOSTIC LIGHTS
The Divert circuit board, Figure 3.12, contains the following diagnostic LEDS:
D3 Processor cycles: should flash
D4 Processor reads serial bus: should flash
D10 Serial bus A input: should flash
D11 On if 24 V DC supply from A is OK
D12 Serial bus B input: should flash
D13 On if 24 V DC supply from B is OK
D14 On if external 24 V DC is applied
D19 Wash relay A on
D20 Wash relay B on
D21 Solids warning relay on
D22 Solids alarm relay on
D23 Divert relay on = not DIVERT (Section 2.2)
D24 Horn on
D25 Refractometer difference relay on = difference alarm
D26 Override
D27 Valve to bypass
D28 Valve to burner
