9 Indicating transmitter specifications 99
** SENSOR TRANSMISSION ERROR ** The signal from the Sensor to the Indicating transmitter is
irregular. The sensor transmission has overrun or there is a
checksum error on the received message. Error is caused by
noise in the sensor transmission.
** NO SENSOR SIGNAL ** The IT-R doesn’t get any signal from the sensor during the
1200 ms measurement interval. This message is normal when
the interconnecting cable is disconnected from either end. In
other cases check the connections and the cable.
** WRONG CONCENTRATION Makes R.I. outside range.
PARAMETERS **
** CONSTANTS ERROR ** Wrong EPROM parameters. Check parameters. If problem
persists, consult authorized service.
** SENSOR INTERFACE FAULT ** Indicates a fault on the processor card of the IT-R, probably a
failure of the sensor interface processor.
Action: Replace the processor card.
EPROM WRITE ERROR Indicates a fault on the processor card of the IT-R, probably
component failure.
Action: Replace the processor card.
PRECONDITIONING A system status message shown every time the preconditioning
(Sanitary refractometer PR-03-A valve is activated by a Relay unit (Section 5.7).
and probe refractometer PR-03-P)
WASH A system status message shown every time when the prism
(Sanitary refractometer PR-03-A wash valve is activated by a relay unit (Section 5.7). If Hold
and Probe refractometer PR-03-P) function is active, the concentration output signal is locked
(Section 5.8) when the message shows.
RECOVERY A system status message shown after wash during the delay
(Sanitary refractometer PR-03-A time when the concentration output signal is still locked (if
and Probe refractometer PR-03-P) Hold function is active, Section 5.8).
HOLD A system status message indicating that an input switch config-
(Sanitary refractometer PR-03-A ured as a Hold switch is closed (Section 5.8).
