Display board 9110 only 9181 only Roche Diagnostics Description of modules The display board contains the LCD display sample contact circuit 9110 only or sample sensor connector the preheater 9110 only and the YES and NO switches used for operation of the analyzer Power and signal interconnection is accomplished via a ribbon cable from the SBC board through JP2 on the display board The sample contact circuit consists of a square wave generator U1B which generates a 500 Hz signal U1A amplifies the signal D2 and C3 rectify the square wave The gain can be adjusted with R10 The sample contact output provides a DC voltage which is proportional to the square wave amplitude During sample aspiration the preheater tube and the sample contact 1 tube are connected to the square wave via relay K1 The heater control circuit controls two transistors which are placed in the preheater block A thermistor provides temperature feedback to the setting of potentiometer R20 The signal difference drives the base of the heating transistors via buffer U2C U2D shuts the system off in case the thermistor opens U2B limits the maximum heating current during warm up U1C and attached circuit is used as an AC DC converter to create negative voltage Vss using square wave generator U1B Display boards utilized in the 9181 analyzer also contain circuitry for both the needle mechanism motor control and position sensor The autosampler Table
