Emerson 200I/48-NT5C05C user manual Volt / AMP digital meter switch, Remote equalize control EQL

Functional description 37

VOLT / AMP digital meter switch

This switch is used to select the measurement display mode of the digital meter. The output voltage or the output current modes can be selected.

VOUT+, VOUT− test points

These test points are used to measure the voltage at the point of regulation. A 5 kohm resistor is placed in series with both sensing leads to prevent short-circuits at the jack terminals. The resistor may affect reading accuracy, depending on the impedance of the meter. Refer to the Instruction Manual for your meter to determine its internal impedance and correction factor.

4.2.6.Float and equalize voltage control

Local FLOAT / EQL switch and potentiometers

The rectifier is equipped with a FLOAT / EQL switch.

When the FLOAT / EQL switch is held in the EQL position, the rectifier goes into equalize mode and boosts the output voltage to the value set by the EQL potentiometer.

When the switch FLOAT / EQL is held in the FLT position, the rectifier delivers a float voltage set by the FLT potentiometer.

Remote equalize control EQL

The rectifier is equipped with remote equalize control. This control is activated by a remote ground signal ( BAT RTN ). The rectifier returns to normal ( float voltage ) operation when this signal is removed.

4.2.7.Current limit adjustment and rectifier regulating test CL ADJ potentiometer

The rectifier limits the output current to a select value ranging from 100 A to 210 A, set by the CL ADJ potentiometer. The factory adjustment is

205 A ±5 A. Extended periods of operation in the current limiting mode and repeated transitions between constant-voltage operation and constant- current operation have no detrimental effect on the performance or service life of the rectifier.
