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 M ETER V OLTAGE /C URRENT C ONFIGURATION
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.

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 W IRING
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.
