The charger output is routed through a relay contact controlled by the microprocessor-based
control system. When the PSC is first connected to a battery cell, the charger output voltage
is automatically adjusted to equal the cell voltage. This way, when the output relay closes,
there is no initial current flow and, therefore, no arcing takes place.
2.2. Selecting the Desired Function
The PSC-10A menu structure lets you select various operating options using soft keys. The
Up/Down Arrow keys, the Mode key, and the Enter key are soft keys, which means their
functions depend upon the menu shown on the display. The functions that the soft keys
perform are displayed on the screen in brackets above the Mode and Enter keys and left of the
Arrow keys. For example, the Cell Voltage screen in Figure 2 shows only one active soft key
that lets you select the Power Supply [PwrSply] mode.
NOTE: This manual refers to the Mode, Enter, and Arrow keys by their soft key names.
3. Power Up
Connect the PSC-10A to a standard 115VAC outlet, attach the charger leads to the front panel,
and set the rear panel power switch to On.
When the unit powers up, the display shows the Albércorp logo and program revision level. The
unit then performs a self-diagnostic and calibration check. A message appears if the diagnostic
detects a problem. If this occurs, cycle the power off then on. If the problem still exists, power
down the unit and contact Albércorp for assistance.
If the self-check is good, the following screen appears:
Cell Voltage
Volts = x.xx

4. Connecting to the Cell
WARNING
: Only connect or disconnect the PSC leads to the battery posts when the PSC is in
the Cell Voltage mode.
After the charger leads are connected to the PSC, connect the red test clamp to the positive
terminal of the cell being charged, and the black test clamp to the negative terminal of the cell.
