When changing the internal Jumper-switch settings, it is always advisable to change the settings
with the 24 VDC power removed. If this is not possible, it becomes particularly important to use
a non-conductive tool to alter switch positions.
Make sure that Jumper- switch settings are fully in position to avoid accidentally leaving a switch in an “in-
between” state.
The total gain range of the amplifier is the product of the IA and variable amplifier gains (variable).
Using the lowest gain switch settings, the net gain is 5 x (1.8 to 18) or 9 to 90
With the other gain combinations available, a 10 volt output can be produced with input voltages ranging from
between 0.002 to 0.50 volts.
2.9 METER VOLTAGE/CURRENT CONFIGURATION
The damped output for a tension indicator can be configured as either a +/- 2V output or a +/- 1mA output by
changing the position of jumper-switch J1 located on the Output Card (Refer to
Figure 4 for location). Voltage
output is selected by setting J2 (1-2). Current output is selected when J2 (2-3 ). Note that different wiring terminals
are employed for the signal return when configured for current or voltage.
2.10 METER OUTPUT DAMPING SELECT
The amount of damping for the meter output (intended to drive a tension indicator) can be configured by the position
of jumper-switch J2 on the Output card (refer to
Figure 4 for location information). Setting the jumper switch to J2
(1-2) sets the break frequency at 0.3 Hz. Setting the jumper switch to J2 (2-3), the break frequency setting is raised
to 3.7 Hz
2.11 WIRING
Most start-up problems are the result of mis-wiring or failure to reference the detailed information in this manual.
While a convenient basic wiring diagram can be found printed on the side label of the amplifier case, the diagram is
intended only as a helpful guide when checking field wiring. Additional information details can be found in the
subsequent sections of this manual and should be referenced before actual installation begins.
