3.2.3 Transition manual control / remote control
In manual control mode the internal control voltage is depending on the effective output voltage. Therefore only very low voltage
drops occur during transition to remote control mode.
During transition from remote control mode to manual control mode, the output voltage will change to the value set with the
voltage control potentiometer with a voltage ramp of 500V/s.
CAUTION!
CAUTION
During transition from remote control mode to manual control mode, the output voltage will change to the
value set with the voltage control potentiometer with a voltage ramp of 500V/s. This can affect the application.
3.3 Current measurement ranges
Each channel has two current measurement ranges. The range can be chosen with the switch labeled with “mA” and “µA” in the
channel control field under the display. In “mA” position, there is an automatic switching between the current measurement
ranges in case of crossing of the threshold. A switching into the lower measurement range will not take place with option
IWP for the case a current limit below the switching threshold is set and this limit already takes effect on the output
current. In position “µA” current measurement will stay in the “µA” range, in case of measurements higher than the threshold
“Overflow” will be displayed.
3.4 Current measurement ranges and current trip
With the current measurement range switch it is also chosen which current trip is active.
• Position „mA“
The commands Lx and LBx are active
• Position „µA“
The command LSx is active
3.5 Safety functions
Each channel has separate safety functions
• Hardware-voltage limit Vmax
The maximum output voltage can be selected in 10%-steps with the rotary switches Vmax (switch dialed to 10
corresponds to 100%). The output voltage is then limited to Vmax.
• Hardware-current limit Imax
The maximum output current for each channel can be selected in 10%-steps with the rotary switches Imax (switch
dialed to 10 corresponds to 100%) Depending on the position of KILL switch, the unit switches into current control
mode or the channel is switched Off
INFORMATION
INFORMATION
Option IWP: With this Option, the 10 percent switch of Imax is replaced with a 10-turn potentiometer.
Smaller steps for current limitation are possible.
