WARNING/CAUTION
When working with active loads, the voltage or current of the active load
must not exceed the maximum voltage or current rating of the BOP. Oth-
erwise the overvoltage or overcurrent protection will shut down the pow-
Never connect the load to the sense terminals. Monitoring instruments
(e.g., DVM, etc.) are the only external equipment that may be safely con-
nected to the sense terminals.
The safety features incorporated into the BOP to handle energy from Ac-
tive loads are unable to protect the power supply or the load if input pow-
er to the BOP is lost or if the BOP Malfunctions. It is recommended that
the user monitor “Power OK” flag pins 3 and 4 of the external Protect Port
(see Table 2-4) and implement a fast-acting means of disconnecting ca-
pacitive loads or crowbarring inductive loads to prevent damage to both
the BOP and the load in the event of input power loss.
For parallel configurations, Remove links between (COM S) and (COM
OUT) terminals of all slaves to prevent damage to the unit and maintain
Connecting multiple units to different a-c input sources may damage the
BOP power supplies and/or the load.
CAUTION: The units are now configured as slave(s) to be controlled only by the master.
Do not use the slave keypad, RS 232 port or GPIB port to try to control the
Pressing RESET will cause voltage transients to appear at the output
which may damage a connected load.
When the ADJUST control is rotated, the active parameter is immediately
effective if the output is enabled (on = STANDBY indicator not lit). The
voltage/current applied to the load changes as the ADJUST control is ro-
When working with active loads, always adjust the BOP protection limits
to be above the maximum values of voltage or current expected from the
load. For example, when the BOP is operating in voltage mode sinking
energy from a constant current type load, set the current protection limits
of the BOP above the maximum current expected from the load.
@
to enter the Saved Waveform Screen from the power-
up screen, perform the following steps to avoid unexpected voltages or
currents from previous settings being briefly applied to the load when the
waveform is first executed.
Pressing RESET will cause voltage transients to appear at the output
which may damage a connected load. Switch is recessed to prevent inad-
When the serial port has received an XOFF, the error message -400, QUE
error will be placed in the queue to indicate the loss of transmitted infor-
mation due to a received XOFF character. When XON is received, the unit
will transmit all data in it's buffer followed by the exclamation character
(!). This (!) character is not part of any message from the BOP and indi-
cates the transmission buffer has been cleared and the BOP is idle.
function is available, perform this function
first, as it affects all other output calibrations.
