MANUAL WASH:
Wash can be initiated from the key A "Start prism wash". This manual wash over-rides the wash stop
logics.
REMOTE WASH START/EXTERNAL HOLD:
This input switch function is described in Section 2.8, paragraph 3.2. It is useful for an intermittent
process: The prism is washed when the process stops and again when it starts. Between those two washes
the output signal is on Hold.
During Hold, the wash cannot be initiated, neither automatically nor manually.
WASH CHECK:
This function can be defined from the prism wash menu, Calibrate/Parameters/Prism wash. A prism wash
is accepted if one of the two conditions are satisfied:
a. TEST exceeds "TEST limit"
b. TEST increases more than "TEST difference"
The default values of "TEST limit" and "TEST difference" are zero, which makes the Wash check inactive.
If one of the conditions are set to zero, the other condition is valid alone. A typical case is "TEST limit" =
230, "TEST difference" = 0. The wash is accepted, if the Test value exceeds 230 during wash, and the Test
difference condition is invalid.
If the wash is not accepted, the diagnostic message will be "Prism wash failure", Section 6.3. This message
is reset from the keyboard "Reset" or by a successful wash. A "Wash retries" parameter can also be set for
repeated wash actions if the wash check fails. The default value is zero.
