ENTRY DESCRIPTION
MODE Power on clock mode. The following two modes can be selected.
STAN Power up in INT (internal) clock mode for stand-
alone operation. This is the only mode for models
without the
–LKS option.
For units with the –LKM option installed, this field is
fixed to CLK/LOCK.
For units with the
–LKS option installed, this field can
be changed to CLK/LOCK for use as an auxiliary
unit in a clock and lock system or to STAND for use
as a stand alone unit.
CLK/LOCK Fixed on master (-LKM) unit configuration in a clock
and lock system. Power up with EXT (external) clock
mode on unit with
–LKS option. (See OPTION menu
section.).
Note that this field cannot be changed if the
–LKM
option is installed.
The frequency resolution below 81.9 Hz in MAST
clock and lock mode is reduced to 0.1 Hz from the
normal 0.01 Hz.
ALC STATE Sets the Auto Level Control (ALC) mode. This mode uses the
internal measurement system to zero regulate the output. There are
three modes of operation:
OFF No measurement based output regulation.
REG Output regulation is enabled. AC source will continuously
regulate output but will not trip off output.
ON Output regulation is enabled and output will fault (trip off)
with Error 801 “Output Voltage fault” if regulation cannot be
maintained and the programmed output voltage is 10Vrms or
higher. No error is generated for settings below 10 volt.
In most situations, the ALC mode should be set to REG or ON for
optimal performance.
Note: The ALC mode only functions for programmed output voltages
above 10 Vrms.
IMP STATE Selects programmable output impedance. The ALC mode must be
turned off for the programmable impedance to be turned on. This
function allows you to change the output impedance (R and/or L) of
the power source.
# OUTPUTS Selects SINGLE or THREE phase mode of operation. The MX15
models operate only in single-phase mode so this field will always
show N/A (not applicable).
