➢
Discharge of waste from the WBC bath
Valve LV14, LV15 and Pump P1 are opened to discharge any waste from the WBC bath.
➢
Discharge of waste from the RBC/PLT bath
Valve LV13, LV15 and Pump P1 are opened to discharge any waste from the RBC/PLT bath.
➢
Discharge of waste from the impedance counting bath
After any waste from impedance counting (RBC/PLT counting) flows through the aperture
and after any waste that results from cleaning the rear section of the RBC/PLT bath flows into
the negative-pressure chamber, Valve LV15 and Pump P1 are opened for waste discharge.
2.2.8 Status Monitoring Module
This module involves:
⚫
Monitoring of V5 DIL
Detection is done by way of a floating sensor; the float moves downwards, the diluent level falls,
and an alarm is activated when it reaches empty.
⚫
Monitoring of V5 LY1
A reflecting optocoupler is used to monitor the V5 LY1 level; as it gets lowe
r, the optocoupler’s
status changes until an alarm is activated once there is no V5 LY1 left.
⚫
Monitoring of V5 LY2
A reflecting optocoupler is used to monitor the V5 LY2
level; as it gets lower, the optocoupler’s
status changes until an alarm is activated once there is no V5 LY2 left.
⚫
Monitoring of waste overflow
Waste overflow is done by way of a floating sensor; as waste levels rise, the float moves upward
until it eventually activates an alarm indicating that it is full.
