Fresenius DPS Visio
Fresenius · Model DPS Visio
Drug Library up to 50 drugs with corresponding concentrations. Bolus injection “hands free” bolus, programmable in amount and flow rate, calculated in dose units or not. Manual bolus, programmable up to 1200 ml/h. Occlusion and pressure management easy setting of occlusion alarm trigger level, up to 1100 mmHg. Line disconnection alarm drop in pressure in the infusion line. Dynamic pressure system (DPS) increase and decrease of the pressure in line monitoring. Anti-bolus system bolus volume reduction at occlusion release. Volume limit and total volume. Battery life: 7 hours minimum, at 5 ml/h.
Key tips
- ·Free-flow protection must be verified on every PM - a failed anti-free-flow clamp is a direct overdose risk.
- ·Test occlusion alarms in both directions - failing to alarm when it should is more dangerous than a false alarm.
- ·Battery run-time complaints are the most common real-world nuisance call - a full charge/discharge cycle test catches most of them.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Failure / error message stops delivery
HighSymptoms: The pump alarms and displays an error message / code and stops.
Root cause: A subsystem fault indexed in the service manual - motor / drive, a sensor, set-detection, or a board.
Occlusion alarm / pressure fault
MediumSymptoms: Repeated occlusion alarms, delivery stops, or an occlusion is missed.
Root cause: Kinked or clamped line, a closed roller clamp, a positional patient tube, pressure-sensor drift, or an improperly loaded set.
Air-in-line alarm
MediumSymptoms: Frequent air-in-line alarms, delivery stops.
Root cause: Air in the set, an improperly loaded set, or an ultrasonic air-detector fault.
Flow-rate accuracy drift
MediumSymptoms: Delivered volume outside tolerance on the annual test, especially at low rates.
Root cause: Worn pumping mechanism / plunger drive.
Battery will not hold charge
MediumSymptoms: Short run time, low-battery early after a full charge.
Root cause: Aged battery pack.
Door / plunger / sensor mechanical wear
LowSymptoms: Set will not load, door will not latch, plunger grip poor.
Root cause: Worn door latch, plunger jaws, or anti-free-flow mechanism.

Er(-)0 or CFPcWhen the device goes into CFPc, you must reconfigure it: WATCH DOG faulty.
Er01Motor rotation fault
Check the motor control. Check the connections. Check the photoelectric cell. Replace the motor
Er32Mechanical advance fault
Check the connectors. Check that the potentiometer is well tightened. Check the calibration. Check the ADC. Check the wear of the half nut by carrying out a counter pressure test of up to 1.4 bars, taking care to install the specific CP wedge. Check the advance in relation to the flow rate. Check the displacement sensor (see Displacement sensor check).
Er82Mechanical fault
COMCommunication fault
Check the lock cover. Check the RS 485 driver. Check the inter-module connection. Check that the PC is communicating with the base. Check the RS 232 driver of the base. Test the serial link with the PC (every 0.5 sec).
CFPcThe configuration self-test when the device is switched on has detected a fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Alarm with an error message / code, delivery stopped
- Note the exact error message or code from the display.
- Look it up in the pump's technical service manual troubleshooting section.
- Run the biomed diagnostics / service utilities to exercise the named subsystem (motor / drive, a sensor, set-detection, a board).
- Follow the manual's parts-replacement procedure for that fault.
- Run the full scheduled-maintenance test set, including a flow-accuracy check, after any repair.
Symptom: Occlusion alarm / pressure fault (or a missed occlusion)
- Check the line for kinks, closed clamps and a closed roller clamp; check the patient site and cannula.
- Reload the administration set correctly, clearing all air.
- Confirm the set is an approved type for this pump.
- Run the pressure-sensor / force-sensor test in the service menu.
- Replace the set; refer the pump if the pressure sensor or pumping mechanism is indicated.
Symptom: Air-in-line alarm / free-flow or feed not delivering
- Prime the set fully and reload it; tap out micro-bubbles at the drip chamber.
- Confirm the set seats correctly against the air-in-line detector / rotor.
- Clean the ultrasonic air-detector window.
- Run the air-detector (or rotor / cassette) test in diagnostics.
- Replace a worn pumping mechanism / anti-free-flow assembly if flow accuracy or detection is out.
Symptom: Battery will not hold charge / short run time
- Fully charge, then run a battery run-down / capacity test in the service menu.
- Check the charging circuit and contacts.
- Replace the battery pack when capacity is below the service limit.
- Recalibrate the battery gauge if the pump supports it.
- Confirm run time meets spec after replacement.
