PowerTRAC Status Inputs Screens

First, the Hand-held Monitor displays 16 screens
showing the states of Status Inputs:

M N T R / C N T L (references) O

S T A T U S I N P U T S

S T S

> r e f f o r c e d i a g

To display additional data, press the F1 ( > ) key.

PowerTRAC Calculated Data Screens

After the Status Inputs, the HHM displays the
block’s calculated data values. Lines 2 and 3
identify the data being displayed and show its
present value. In the example below, voltage A to
N is 117 volts.

PowerTRAC Extra Calculated Data (LPIO)
Screens

If the PowerTRAC block is version 2.3 or later, the
Hand-held Monitor next shows a series of screens
with extra calculated (“Low-Priority I/O”) data.
The block may or may not automatically provide
this data to the host, depending on the block’s
revision level and configuration. A CPU can use
datagrams to read the data.

On these screens, the top line shows the serial bus
address of the block and the relative data word
being displayed. For example, the screen above
shows the 20th input word (Fundamental VARs
for phase A). This area of line 1 blinks as a
reminder that the numbers shown are not
reference addresses.

PowerTRAC Control Outputs Screens

Finally, the HHM displays 16 screens showing the
states of individual Control Outputs (datagram
handshaking bits). If you use the F1 ( > ) key to
reach the Control Outputs, notice that there are
several unused references following the Extra
Calculated Data data. You can use F2 (ref) to go
directly to output 1. You may need to toggle the
memory type to %Q (or O, depending on the host
CPU setup of the HHM).

Forcing PowerTRAC Data

(The HHM’s circuit forcing capability must be
enabled to perform this function). Display the
data you want to force. Press F3 (force).

For bit data

, the HHM displays:

m o n o n o f f r e l e s

Press F2 (on) or F3 (off). To release the force, press
F3 (reles).

For word data

, the HHM displays:

Press F2 (force). The screen next displays:

F O R C E T O :

c h n g e n t r

Press F2 (chng). Enter the force value, then press
F3 (entr). To release the force, press F4 (release).

Diagnostics

The PowerTRAC block does not report circuit
faults. If you use the F4 (diag) key from the
Monitor/Control Reference screen, the message

NO FAULTS

will appear.
