. Version 1.1
3.2. Selecting 6020HRJ or 8030J Operation
When ALL FOUR jumpers (J1-J4) are connected, the amplifier must operate as a
6020HRJ. When ALL FOUR jumpers are disconnected, the amplifier must operate as an
8030J amplifier.
3.3. Input/Output Connections
3.3.1. AC Inputs (TB1-9, 10 TB2-13, 18, 19)
115VAC, 50/60 Hz, 50 VA are required for the cooling fan. The connections are made at
TB1-9 and 10. Always make sure that the fan is operational before operating the
amplifier. The AC input for the power amplifier is made at terminals TB2-18 and 19 with
TB2-13 connected to the center tap of the source. The following 50/60 Hz voltages
should be used (refer to Figure 3-1).
For 6020HRJ operation, use 80 VAC center tapped (C.T.) ±10%.
For 8030J operation, use 110 VAC (C.T.) ±10%.
Use only terminal TB2-13 for the center tap connection.
3.3.2. Motor Connections (TB2-16, 17)
The motor is connected between terminals TB2-16 and 17. Make sure the correct motor is
being applied to the amplifier. Check for shorts between motor leads and ground and
between motor leads before connecting the motor to the amplifier. A choke may have to
be inserted if motor inductance is too small. Total inductance must be greater than .75 mH
for 6020HRJ and 2.2 mH for 8030J operation.
3.3.3. Supplies for External Use (TB2-11, 12, 14, 15, TB1-4, 6, TB2-
13 Common)
Reg15 VDC, 30 mA DC maximum at terminal TB2-12 and –15VDC, 30 mA DC
maximum at terminal TB2-11 are available with respect to commons TB1-4, 6, and TB2-
13. Unregulated bus voltage (60 VDC nominal 6020HRJ, 80 VDC nominal for 8030J) is
available at TB2-14 and TB2-15.
The current drawn from this load current should not exceed the continuous
current capability of the unit. The common for this supply must be TB2-13.
3.3.4. Pre-Amplifier Inputs (TB-1, 2, 3, 5, TB1-4 Common)
Four inputs are available for input and feedback signals. Inputs 1, 2, and 3 (TB1-1, 2, and
3 respectively) sum to the inverting input of the pre-amplifier. TB1-5 provides a non-
inverting signal to the pre-amplifier. In addition, TB1-1 and TB1-5 provide a differential
input for attenuating common mode from remote signal sources. All input signal
commons should be connected to TB1-4 or 6.
3.3.5. Directional Current Limits (TB1-6, 7, and 8)
TB1-6, 7, and 8 are available to inhibit current of a specific polarity for limited travel
loads. Connecting TB1-6 to TB1-7 limits current between output terminals TB2-16 and
TB2-17 at 3 amps or less without inhibiting current between TB2-17 and 16. Likewise,
connecting TB1-7 to TB1-8 limits current between TB2-17 and TB2-16 at 3 amps or less
without inhibiting current between TB2-16 and TB2-17. Connecting TB1-6 to TB1-8
limits current in both directions at 1 amp or less.
