Power-On and Reset Conditions Elgar CW-P Series
2-2 Programming Manual
In addition, unique system settings are read in from the non-volatile EEROM memory:
Output Relay State, either Auto Start or Standby
Keyboard Lock State, either Front Panel Program Enabled or Disabled
Master/Slave status if part of a multi-unit configuration
2.3 Reset Conditions
When the *RST command is sent via SCPI, the following conditions apply:
Faults are cleared
The error queue is cleared
The output relay is opened
VoltsA, VoltsB, VoltsC are set to 0
A locked keyboard remains locked.
2.4 Changing Voltage Ranges Via Command Interface
When the voltage range is changed using the command interface:
SOUR:VOLT:RANGE 1
If moving from low range to high range, and the output relay was initially in the closed
state, the CW will open the output relay. In this case, the programmer must re-close the
relay and set the new voltage.
2.5 Changing Ranges During Recall Via Command
Interface
Assume that the CW is in low range with the output relay closed and sourcing 100 volts.
If a recall is performed:
SYST:RECALL 33
And the recalled system state was initially saved in high range, the output relay will
open, the new system values will be read into the CW parameters, the CW will shift into
high range, and the output relay will re-close. The entire process takes approximately
two seconds. The CW cannot change ranges seamlessly with the output relay closed
during the transition.
