Section 7
Maintenance
7.1 Overview
The analyzer is designed for automatic trouble-free operation under the continuous
supervision of the internal computer. As described in Sections 4 and 5, a series of alarms are
presented on the hand held keypad and the application program if an operation or function is
not performing in the appropriate manner to alert the user that a problem exists. A detailed
discussion of service protocols is presented in Section 8.
Routine Preventative Maintenance of the analyzer consists of a periodic performance of the
Maintenance Check-out Procedure (Section 7.2). Routine maintenance will typically
correspond to tape usage, which is 4 – 6 weeks for most applications.
On a periodic basis, it will be necessary to replace certain components of the system such as
the sensing tape, the quartz tube in the total sulfur accessory the H
2
S filter and the liquid in
the humidifier. Replacement procedures for these items are described in Section 7.3-7.6.
A series of videos demonstrating typical maintenance procedures for the ProTech903
analyzer is available on Galvanic Applied Sciences Inc.’s YouTube channel (search YouTube
for Galvanic Applied Sciences).
7.2. Routine Maintenance Procedure
a) Check display for any alarms (press F2 on keypad). Refer to Section 8 for how to resolve
