2.8.4 OPERATING INSTRUCTIONS FOR MULTIPLE UNIT COMBINATIONS
1. Before either installing the units in a rack or stacking and connecting them one on top of the
other, configure the power-up settings as desired while the units are turned off.
a. For master unit, perform the Reset Power-up (see PAR. 3.3.2.1) to establish the load type,
logic for trigger port pin 2 (output on/off) and RS 232 baud rate (this also resets limits to
factory default settings (see PAR. B.143).
b. Configure the master/slave power-up switches (S2-1 through S2-5) for each unit per Table
2-2.
c. Configure the mode control power-up switches (S3-1 through S3-5). For analog control
refer to PAR. 2.7.2, for digital control via GPIB refer to PAR. 2.7.3 and for digital control via
RS 232 refer to PAR. 2.7.4.
NOTES: • It is not necessary to set power-up switch S3 segments for the slaves. Power-up
configuration is established automatically: mode of operation is established by the
series or parallel configuration switch S2-2 of each unit, the analog inputs are dis-
abled, and the limit channels are set for maximum internal values
• After setting the power-up switches S1 through S3, turn on each unit for approxi-
mately 10 seconds to allow the unit to store the settings. Then turn off the units and
proceed to step 2.
2. Install the units in the rack, or stack them one on top of the other, then use the cables and
terminations supplied in the applicable Interconnection Kit (available as an accessory, see
Table 1-5) per Figures 2-8 through 2-11 as applicable. Figures 2-7 (local sensing) and 2-8
(remote sensing) show the connections for three parallel-connected units; Figures 2-9 (local
sensing) and 2-10 (remote sensing) show the connections for three series-connected units.
These figures allow other configurations, e.g., two parallel-connected units or two series con-
nected units, etc. to be easily deduced.
CAUTION: For both parallel and series configurations, remove links between (COM S)
and (COM OUT) terminals of all slaves to prevent damage to the unit and
maintain system accuracy. Make sure to accurately follow Figures 2-7
through 2-10 for proper connection of the units.
3. Connect all units to a common a-c power source.
4. Connect the load to the master power output terminals using wires rated for the total current
and voltage of the system. For remote sensing use a twisted pair #22 AWG to connect OUT
S to OUT and COMM S to COMM at the load (see Figure 2-8 for parallel or Figure 2-10 for
series).
5. Connect monitoring/measuring devices to the master as shown in Figure 2-6.
6. Turn on all units, starting with the master. After the start-up sequence has ended, each unit
should not be beeping, the POWER/FAULT/LIMIT lights should be green, and the MASTER/
SLAVE lights should correctly identify master (green) and slaves (yellow).
