If remote voltage control (see PAR. 3.4.2) is not enabled, the front panel Vadj trimmer (see PAR.
3.4.1) provides adjustment of the output voltage within the limits specified in Table 2; test points
are available at the front panel for monitoring the DC output.
Figure 5 shows the location of all operating controls, indicators and test points followed by an
explanation of each.
•
VDC ON/ALARM indicator. Lights green when unit is operating (MZ models permit selection of indi-
cator power, either from HSF output or internal reference, see PAR. 3.4.3). When enabled by DIP
switch configuration, lights red to indicate loss of output voltage in parallel configuration only (see
PAR. 3.8.1).
•
V.ADJ Output voltage adjustment trimmer: Adjusts output voltage within limits specified in Table 2
(see PAR. 3.4.1). Not functional if remote voltage control is enabled (see PAR. 3.4.2).
•
TEST POINT (+, –): Connect to voltmeter to monitor d-c output voltage.
•
OUTPUT RESET switch. Used to recycle power in the event of an alarm condition (see PAR. 3.7).
Not functional when remote on/off control is enabled (see PAR. 3.5).
•
POWER ON/OFF switch. Applies power to the unit.
CAUTION: Power must be OFF before unit is
removed from the rack adapter.
•
Retaining Latches (2). Prevents inadvertent removal of unit from rack adapter (see PAR. 3.10).
•
Voltage/Current meter: Monitors output voltage or current according to setting of Meter Mode switch.
NOTE: Use remote sensing for voltmeter to display voltage at the load.
•
Meter Mode slide switch: Set to V for display to show output voltage, set to A to show output current.
•
V indicator: Lights green to indicate meter is showing Volts.
•
A indicator: Lights amber to indicate meter is showing Amperes.
