SCREEN 2: INPUTS / OUTPUTS (Cont.)
!HEPAL = No heparin pump alarm? No alarm = 1. Pin C25 on the motherboard connector P1.
!SNGNE = Single needle (venous) blood pump not running? Venous blood pump running = 0.
During single needle operation, when the arterial blood pump runs, the venous blood
pump does not and vise versa. This pin monitors the blood pump during so that the
functional board can control the venous clamp. When the arterial blood pump runs, in
single needle operation, the venous clamp is closed. Pin C26 on the motherboard
connector P1.
!BPSTP = No blood pump(s) stopped alarm? Blood pump (arterial or venous) stopped alarm = 0
(low). If the blood pump(s) are turned on this pin will = 0 15 or 30 seconds after the
blood pump(s) stopped stop for any reason. Pin C27 on the motherboard connectorP1.
VENBP = Operational venous (single needle) blood pump present? Pump present = 1. This pin
must = 1 in order to turn single needle function on. Pin C28 on the motherboard
connector P1.
!LD AL = No level detector alarm? No level detector alarm = 1. Pin C24 on the motherboard
connector P1.
V12 OK = +12 Vdc ok? This power logic board constantly monitors the +12V power supply and
inform the functional board of its state via this pin (motherboard P2 connector, pin
A21). 12 +/-0.3 Vdc = OK. If the voltage is outside this range the functional board
will issue a 12 volt high or low alarm
VNTVLO = Vent valve open? Open vent valve in self prime = 1. The vent valve is located inside
the level detector module and vents the venous drip chamber to atmosphere when open.
This pin does not go high when manually raising the venous level. Pin C15 on the
motherboard connector P1.
CLAMPO = Venous bloodline clamp open? Open clamp = 1. Pin C16 on the motherboard
connector P1.
CLR AL = Clear alarms? Reset alarms to modules = 1. NOTE: This occurs to quickly to be seen
in DEBUG. Pin C17 on the motherboard connector P1.
!BPSTP = No blood pump stopped? Stop blood pump(s) = 0. Pin C18 on the motherboard
connector P1.
BPSPEC = Blood pump special? Special blood pump control = 1. This pin inputs the blood pump
module and controls the blood pump to a maximum speed of 150 ml/min. This occurs
whenever the venous level switch is held up to raise the venous drip chamber level. Pin
C19 on the motherboard connector P1.
RINSE = In rinse? In rinse program = 1. Pin A22 on the motherboard connector P1.
!FLOW = No flow? Flow off = 1 with no water alarm. Pin A23 on the motherboard connector P1.
!RELPR = No release pressure? Release dialysate pressure = 0. This occurs when resetting a
TMP alarm. This pin in not connected. Pin A24 on the motherboard connector P1.
!DIAAL = No dialysate alarms? Dialysate alarms = conductivity or temperature alarm or shunt
door open = machine in bypass = 0 i.e. valve 24 closed, valve 26 open. NOTE: This
pin is not connected. Pin A25 on the motherboard connector P1.
