Adjusting Track Air

When you switch between devices of different sizes, to make sure that the

devices advance smoothly down the track into the output tube, you may

need to adjust the track air. See Figure 4-32 for the location of the track air

adjustment knob.

Preventive Maintenance

This chapter describes ProMaster 2500 theory of operation, diagnostics,

and preventive maintenance procedures. Diagnostic tests are described

for the motors, solenoids, optics, switches, and programming electronics.

The information in this chapter is presented in the following order:

Theory of Operation................................................................................5-2

Conditions Requiring Corrective Action ...........................................5-21

Corrective Adjustments........................................................................5-24

Diagnostics .............................................................................................5-30

Preventive Maintenance Procedures For Operators ........................5-55

Preventive Maintenance Procedures For Service Technicians........5-60

WARNING:Performing some of the diagnostic procedures in this

chapter will expose you to harmful high voltage. To avoid

electrical shock or mechanical injury, only a service

technician trained on electromechanical equipment

should perform the diagnostic tests that require lifting the

main plate while the 2500 is on.

Theory of Operation

This section describes the operation of each of the ProMaster 2500’s major

components.

TaskLink

You will normally operate the 2500 under the system control of the

TaskLink software program, running on a personal computer (PC).

TaskLink uses a set of computer remote control commands to

communicate with the 2500. These commands control the programming,

handling, labeling, and binning operations of the 2500.

During a typical communication sequence between TaskLink and the

2500, TaskLink issues a command to a subsystem, then yields control to

that subsystem and waits for a reply. The communication sequence will

usually occur in the following manner:

1. TaskLink sends a program command to the Programming Electronics

(PE) subsystem and waits for the PE to complete the procedure.

2. When the PE has completed the procedure, it sends a signal to

TaskLink indicating whether the device has passed or failed.

3. If the device passed, TaskLink looks at the task to determine what

additional procedures need to be performed. TaskLink then sends

the next command to the 2500.

If the device failed, TaskLink displays an error message on your PC

monitor. If the error is related to device testing or programming, the

error code is recorded in a log file on the hard disk of your PC.

Error messages are described in Chapter 6.

4. When a device passes the programming/verify operation, TaskLink

receives a category signal from the programming electronics, and

sends it to the 2500. The 2500 checks the signal against the bin map

and processes the device accordingly.

Device Processing

This section describes the flow of a device through the 2500. A device

travels from the input tube to the programming station, then to the

labeling station (if the device passes the verification tests), and then to

one of two output tubes.

Device Moves to

Programming Station

A device travels from the input tube to the programming station in the

following manner:

1. When TaskLink runs a task, it prompts the handler to perform a brief

self-calibration initializing routine before loading the first device.

One of the checks performed during this routine is to see if the hood

is raised. If the hood is raised, the handler displays a warning

message prompting the operator to lower the hood before continuing

the task.

2. The operator inserts a tube containing blank (unprogrammed)

devices into the input tube holder. This action is detected by the

input tube holder microswitches (19 in Figure 5-3).
