Section 7

MAIN TENANCE

7.0 General

T his Section describes maintenance proce

dures for the IQ Data. T he information contained here is
divided as follows:

•

Isolating a malfunction (Par. 7.1)

•

Replacing the IQ Data (Par. 7.2)

DATA

Earlier Sections of this Manual, especially Section 2, Hard

ware Description; Section

Operator Panel; and Section

Installation and Startup, should be read thoroughly to familiar

ize the maintenance person with the

Data.

Table 7.A

INITIAL POWER-ON T ROUBLESHOOTING

Symptom

Probable Cause(s)

Solution

All Operator Panel indicators are off.

•

Control power is deficient.

•

Locate deficiency in control power

line.

7.1 Troubleshooting -

This Paragraph describes the follow

ing procedures:

•

Troubleshooting when AC power is first applied to an IQ
Data in an application (Par. 7.1.1).

•

Troubleshooting assuming the IQ Data has been installed
and was operational for a period of time (Par. 7.1.2).

7.1.1 Initial Startup -

This Paragraph lists procedures to fol

low when the IQ Data is not operating properly after AC power
is first applied. The procedures assume that:

•

All steps listed in Paragraphs 4.4.1 and 4.4.2 have been
completed, and

•

One or both display windows do not display values and/or

the lA AMPS RMS LED or V AB VOLTS RMS LED are not
lit.

Shaded area designates information that

replaces or supplements applications using
the 3-phase Power Module.

•

Replace unit. (See Paragraph 7.2)

All maintenance procedures must be performed only by

qualified personnel who are familiar with the IQ Data and

the associated AC lines being monitored. Failure to observe
this caution can result in serious or even fatal personal

injury and/or equipment damage.
The following procedures at times involve working in equip

ment areas where the hazard of fatal electrical shock is

present. Live parts are exposed. Personnel must exercise
extreme caution to avoid injury, including possible fatal

injury.

Always disconnect and, if necessary, lock out the AC power
source before touching the components on the rear of the
IQ Data. Failure to do so can result in serious or even fatal
personal injury and/or equipment damage.
