GeneralDescription
1.I Introduction
This manual provides service information for the Flo-Gard@ 6201 Single Channel Volumetric
Infusion Pump (product code 2M8063) for qualified hospital biomedical engineers and service
personnel. Seethe pump’s Operator’s Manual for detailed operating instructions.
1.2 Features
The Flo-Gard@ 6201 Single Channel Volumetric Infusion Pump is anelectromechanical pump
usedfor the intravenous infusion of liquids at user-selectedrates. The pump contains a linear
peristaltic pump head which is programmable andpermits infusion of primary and secondary
medication programs. The secondary program automatically switches over to the primary pro-
gram when secondary infusion is complete (automatic piggybacking).
The pump operateson standard 115 VAC 60 Hz electrical power, or on its self-contained re-
chargeablebattery. It is portable and has a panel lock-out feature to prevent patient tampering. It
is designed for usewith Baxter’s standard administration setswhich contain an “s” asthe last
characterof the code number, for example, 20537s. When infusing solutions through a central
line catheter, setswith a Luer lock adaptershould be used. Sets with a Flashball@ device are not
recommended in theseapplications.
The primary rate of infusion is selectable from 1to 1,999 mL in 1mL/hr increments and 1.Oto
99.9 mL/hr in 0.1 mL/hr increments. The secondaryrate is selectable from 1 to 999 mL in 1
mL/hr increments and 1.Oto 99.9 mL/hr in 0.1 mL/hr increments. The volume to be infused
(VTBI) is also selectable from 1to 9,999 mL in 1 mL increments and 1.0to 99.9 mL in 0.1 mL
increments.
The total volumes infused from primary and secondaryprograms areadded together and accu-
mulated and can be displayed on demand. The primary and secondary VTBIs areindependently
decremented and displayed. Upon completion of the primary VTBI, the pump automatically
switches to a keep vein open (KVO) rate. If the pump is startedon a secondary rate and VTBI,
the pump will change to the primary rate when the secondary program is completed. The pump
may be stopped at any time by pressing the STOP key unless the pump is in the lockout mode.

General Description
The Programmed Delivery Profile (PDP) enables manual programming or ramped calculation
(available only on pumps running software versions 1.09or later) of up to 10 sequential infusion
programs for situations where multiple flow ratesareindicated. Seethe appropriate Operator’s
Manual for additional information.
1.2.1 Nurse Call
The Nurse Call feature is enabledby installing ajumper wire to the Terminal Printed Circuit
Board at the location labeled R421 on the board. When thejumper is connected, the Nurse Call
relay will be energized only during an alarm condition and when the ALARM LED is lit. The re-
lay contact points (normally closed, normally open, andcommon) are accessible from the COM-
MUNICATIONS PORT on the rear of the pump (pins 1,4, and 9, respectively). The Nurse Call
feature may be used when the pump is connected to a computer, however, provisions must be
made at the communications port to connect both options simultaneously. Specifications for the
9-pin D connector arelisted under Technical Specifications.

1.4 Controls and Indicators
All controls and indicators are shown in Figures l-l, 1-2, and l-3. Service personnel should be
familiar with the pump’s features and operation before servicing the pump.
The pump’s serial number is recorded on a label on the back of the pump.
ITEM FUNCTION
1.Message Display Shows all messages.
2. BACKLIGHT key
3. SILENCE Key
Provides backlighting of the displays when the pump is
used in darkened areas.The key toggles the backlighting
on and off. If the pump is operating on battery power, the
backlight remains on for 60 secondsand turns off automat-
ically to conserve battery power.
Temporarily silences an audible alarm or alert for two min-
utes. All visual alarm or alert information remains dis-
played.
4. NEXT Legend When the NEXT legend is lit, the TOT VOL/STATUS key
functions as a scrolling key to advance to the next step of a
programmed delivery profile (PDP) or configuration op-
tion. SeeSection 1.5.

Detects a complete tubing restriction upstream of the pump.
Linear peristaltic pump mechanism.
Detects misloaded tubing out of the channel guide slots.
Detects a complete tubing restriction downstream of the
pump.
Detects air bubbles in the IV set.
Prevents accidental fluid flow when the IV set is properly
loaded and the pump door is opened.
Provides an additional means of preventing accidental
gravity fluid flow by occluding the tubing in the admini-
stration setwith the slide clamp before the set can be re-
moved from the pump. The use of this feature is optional;
when used, the slide clamp must be loaded in the slide
clamp slot. The feature is selectable through the pump’s
configuration options. If alert mode is enabled, the pump
will operate without the slide clamp inserted and the IN-
SERT SLIDECLAMP messageis displayed. An alert tone
will sound to notify the userthat the slide clamp should be
inserted. If the alarm mode is enabled (software versions
1.09or later), the pump will NOT start and an alarm tone
will sound if the slide clamp is not loaded.
The pump is shipped from the factory with this plastic in-
sert in the slide clamp slot. It prevents damage to the
mechanism during shipment and maintains the proper
spring tension. If your hospital does not plan on using the
slide clamp feature, Baxter recommends that this plastic in-
sertremain in place during use. SeeSection 6.3.15.
Function asa guide to keep the tubing properly aligned
over the pumping fingers.

General Description
1.5 Configuration Option Feature
This section describes the configuration option feature of the pump, which allows qualified per-
sonnel to inspect and/or modify certain pump operating parameters to suit customer require-
ments.
These parameters andtheir setting options are shown in Table 1-1. The factory settings made at
the time of manufacture arealso shown in the table.
Note: Although the configuration option data is stored in battery backed-up
RAM, it may be lost if the main battery connector (CN302) is discon-
nected from the CPU board without turning off the device. The con-
figuration option data is also lost if the lithium backup battery
connector (CN304) is disconnected while the main battery is discon-
nected. Therefore, we advise that the configuration options be re-
corded before beginning repair procedures and reset when repairs
are complete.
