KLN 750W 121912
To operate units connected in parallel, proceed as follows:
1. Verify that the units are connected as shown in either Figure 2-13 (without remote compen-
sation) or Figure 2-14 (with remote compensation)
2. Verify that Programming Control Port connections are as shown in Figure 2-15.
3. Turn on Master unit first, then Slave units.
4. Set menu function for Ramp Down Time of Master to 0 (see PAR. 3.3.11).
5. Set PSOP (Parallel/Series operation) function in the menu to PM (Parallel Master) for the
Master unit and to PS (Parallel Slave) for the Slave unit (see PAR. 3.3.24). After setting
PSOP, output ON/OFF of the series combination is controlled by the Master.
6. Set OVP and OVC of the Slave(s) to a higher value than that for the Master to ensure that
overvoltage and overcurrent protection work properly.
7. When powering off a parallel combination, first turn off the Slave(s), then the Master.
3.4.4 DISCONTINUING PARALLEL OPERATION
To allow units connected in parallel to function independently, proceed as follows:
1. Turn off power to Slaves, then Master.
2. Disconnect all parallel connections shown in either Figure 2-13 (without remote compensa-
tion) or Figure 2-14 (with remote compensation), including SER IN connections.
3. Disconnect Programming Control Port connections shown in Figure 2-15.
4. After turning on each unit, set PSOP (Parallel/Series operation) to PM (Parallel Master) in
the Menu (see PAR. 3.3.24).
3.5 ANALOG REMOTE MODE PROGRAMMING
The KLN 750W can be programmed remotely using analog signals applied to the remote Pro-
gramming Control port at the rear panel (see Figure 2-1 and Table 2-4). Analog remote pro-
gramming allows the user to 1) control output on/off (PAR. 3.5.1), 2) initiate emergency
shutdown of the output (PAR. 3.5.2), 3) control output voltage (PAR. 3.5.3) or current (PAR.
3.5.4) and 4) monitor power supply status (PAR. 3.5.6).
3.5.1 REMOTE OUTPUT ON/OFF
The output can be set on or off using the Programming Control port pins 21 and 25. When the
pins are shorted the output is on, when they are open the out is off. This can be accomplished
using either an optocoupler or relay. (See Figure 3-4). This feature must first be enabled from
the front panel by setting external control of output on/off to ON (see PAR. 3.3.25).
