Wiring via PTs (PT Ratio > 1):
Vmax (690 V input option) = 144 × PT Ratio [V]
Vmax (120 V input option) = 144 × PT Ratio [V]
Pmax = (Imax × Vmax × 3)/1000 [MW x 0.001] @ wiring modes 4Ln3, 3Ln3
Pmax = (Imax × Vmax × 2)/1000 [MW x 0.001] @ wiring modes 4LL3, 3OP2, 3dir2, 3OP3, 3LL3
NOTE: Pmax is rounded to nearest whole kW units.
The actual frequency range is 45.00 - 65.00 Hz
When the 4LN3 or 43LN3 wiring mode is selected, the voltages will be line-to-neutral; for
any other wiring mode, they will be line-to-line voltages.
4.6 Analog Expander Setup Menu
By connecting two optional AX-7 or AX-8 analog expanders (with outputs of 0-20
mA, 4-20 mA, 0-1 mA or
±1mA) to the PM296/RPM096, an additional 14 (with
AX-7) or 16 (with AX-8) external analog output channels can be provided. This
menu allows you to select an output value, and its zero and full scales, for these
extended channels.
Channels A1-1 to A1-8 correspond to the first analog expander, and channels A2-
1 to A2-8 correspond to the second one. The setup menu operates in the same
way as the Analog Output Setup Menu (see Section 4.5).
NOTES
1. The analog expander outputs operate through communications port COM2 in RS-422
and RS-485 mode. In both cases, connections between the instrument and the analog
expander should be made using four wires.
2. Settings you made for analog expander outputs will not be in effect until the analog
expander output is globally enabled in the instrument. To activate the analog expander
output, set the analog expander option in the User Selectable Options setup (see
Section 4.11) as it is set in your expander. Do not enable the analog expander output
when you do not have the analog expander connected to the instrument, otherwise the
computer communications will become garbled.
3. If you have the analog expander connected to your instrument, you will not be able to
communicate with the instrument via a PC until you enable the analog expander option
in the User Selectable Options setup (see Section 4.11). If this option is enabled,
communications will be successful whether or not the analog expander outputs
operate.
