NAME OF FUNCTION
FUNCTION
NOTE: NUMBERS CORRESPOND TO THOSE SHOWN IN FIGURE 2-2
1
A-C POWER
A-C input Power Switch and Indicator Lamp
2
OUTPUT
Output “READY” lamp energized when a-c power is turned on. If lamp goes off
when a-c power is applied, the internal protection circuit disables the output
and front panel controls. To restore full operation it is necessary to turn the
power supply OFF and then ON again after a few seconds.
3
± OUTPUT, COMMON, GROUND
Output and grounding terminals (parallel with rear barrier strip terminals)
4
MODE
Operating mode selector switch for “VOLTAGE” OR “CURRENT” mode
5
Mechanical voltmeter zero adjustment
6
Mechanical ammeter zero adjustment
7
VOLTAGE LIMIT
LED lamp, indicating voltage limiting operation
8
± VOLTAGE LIMIT
Controls for manual adjustment of the (±) voltage limits
BOP 500M BOP 1000M
A = 500V TO 0 -1000V TO 0
B = 0 TO +500V 0 TO +1000V
9
EO INPUT
Programming input terminals for voltage pre-amp
10
BIPOLAR VOLTAGE CONTROL
“ON-OFF” switch and voltage control for manual adjustment of the BOP d-c
output voltage (with switch “ON”)
11
EO METER
d-c output voltmeter (reads also average a-c signals)
12
EO MODE
LED lamp, indicating voltage mode operation
13
CURRENT LIMIT
LED lamp, indicating current limiting operation
14
± CURRENT LIMIT
Controls for manual adjustment of the (±) current limits
BOP 500M BOP 1000M
A = -80mA to 0 -40mA to 0
B = 0 to +80mA 0 to +40mA
15
IO INPUT
Programming input terminals for current pre-amp
16
BIPOLAR CURRENT CONTROL
“ON-OFF” switch and current control for manual adjustment of the BOP d-c
output current (with switch “ON”)
17
IO METER
d-c output ammeter (reads also average a-c signals)
18
IO MODE
LED lamp, indicating current mode operation
19
FUSE
a-c power fuse. Protects primary a-c input circuit
20
a-c power input jack. Accepts 3-wire line cord (supplied)
21
Cable holder, accepts output, sensing and ground wires for feed-through from
terminals through safety cover
22
REAR TERMINALS
Rear barrier strip with output, sensing and ground terminals
23
INTERLOCK
Shuts off BOP if safety cover is removed. Can be defeated by a forward pull
24
INT. IOX CONTROL
R303, compensation adjustment. See Section 5.
25
REAR CONNECTOR
Access to internal circuitry for programming connections
26
INT. CONTROLS
R31, R36, Current and voltage pre-amp zero controls
27
INSULATED TOOL
Use this tool for all internal adjustments
