Nilfisk-Advance CS7000 Service Manual

Solution System 322Service Manual – CS7000
Circuit Description
The Following Conditions Must be Met for the Solution System to Operate
• The Hopper Interlock Switch S3 must be closed.
• There must be positive voltage to the J7-1 Interlock Input. For this to happen:
– The Seat Switch S9 must be closed.
– The Safety Relay K14 on the Steer By Wire Controller A5 must energize the coil to close the Safety Relay
K14
contactor.
– The Emergency Stop Switch S15 must be closed.
– The Battery Interlock S13 must be closed (battery machines) or jumpered (Diesel and LP machines).
• The 400-amp Fuse F1 must be closed to provide positive voltage from the Battery to the load side of Auxiliary
Contactor K9
.
• The Ignition Switch S14 must be closed to provide positive voltage to the Auxiliary Contactor K9 coil. The
J2-14 Output on the A1 Main Machine Controller provides ground to the Auxiliary Contactor K9 coil when the
Ignition Switch S14 provides an input to the Key Switch Input J7-12.
• The Auxiliary Contactor K9 must be closed to provide positive voltage to circuit breakers VACC1/CB1 and
VACC2/CB2.
• Circuit breaker VACC1/CB1 must be closed to provide positive voltage to Solution Valve L1.
• Circuit breaker VACC2/CB2 must closed to provide positive voltage to the Solution Control Pump M19
(EcoFlex™ machines only). (Note that VACC2/CB2 must closed to provide positive voltage to the Extended
Scrub Pump M25
and Low Pressure Pump M23 as well.)
• The J2-20 PWM Output provides negative ground to Solenoid Valve L1, and the J3-2 PWM Output provides
negative ground to the Solution Control Pump M19 under the following conditions:
– The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that the
operator has pressed the scrub switch.
– The A1 Main Machine Controller must receive a signal from the A2 Drive Controller via the CAN BUS that
the machine is moving forward or (optional) in reverse.
The Following Conditions Must be Met for the Extended Scrub System to Operate
The extended scrub system requires the same conditions to operate as does the solution system, with the
following additions:
• The extended scrub function must be installed in the conguration menu.
• The J3-1 PWM Output provides the negative ground to the Extended Scrub Pump M25 under the following
conditions:
– The A1 Main Machine Controller must receive a low-solution signal via the CAN BUS from the A3 Control
Panel
.
– The A1 Main Machine Controller must receive a signal from the A3 Control Panel via the CAN BUS that the
operator has pressed the extended scrub switch.
– The A1 Main Machine Controller must receive a signal from the A2 Drive Controller via the CAN BUS that
the machine is moving forward or reverse.
