BOP 5-20DL 081915
2.5 PRELIMINARY CHECKOUT
NOTES: 1. The Rear Programming Connector supplied with the unit (PC-15) is prewired for
local control (see Simplified Schematic Diagram, Figure 3-29) and must be attached
to the BOP. The PC-12 Rear Programming Connector is unwired and available as
an accessory.
2. With either no signal or logic 0 at OUTPUT ON-OFF Port pins 2 and 3, output volt-
age (in voltage mode) or output current (in current mode and a load connected) will
have the preadjusted output value. See Table 1-1 and PAR. 4.2.5 for details.
3. If the unit is in current mode with no load connected and either no signal or logic 0 is
applied to OUTPUT ON-OFF Port pins 2 and 3, the unit will go into voltage limit, dis-
playing the preadjusted limit value with the same polarity as the output current off-
set. The front panel Voltage Limit indicator will go on and the Current Mode indicator
will go off.
A simple operating check after unpacking, and before permanent installation, is advisable to
ascertain whether the BOP has suffered damage in shipment. Refer to Figures through 2-2 and
Tables 2-1 and 2-2 for the location and function of the operating controls and terminals. Proceed
as follows:
1. Connect the BOP to a 115V a-c source, or refer to paragraph 2-4 for conversion to other a-
c input voltages if required.
NOTE: The rear sensing links must be attached to the rear barrier strip (TB201) of the BOP as
shown in Figure 2-2 and the Rear Programming Connector (PC-15) must be attached
and secured.
2. Set the BOP front panel controls as follows. The controls are identified with the nomencla-
ture used in Table 2-1 and the identifying numbers used in Figure 2-1.
a) Set MODE switch (6), to VOLTAGE.
b) Set VOLTAGE CONTROL switch (2), to ON, and rotate VOLTAGE control (3) to its
maximum counterclockwise position.
c) Set a-c circuit breaker/POWER switch (1) to ON.
3. At the rear panel, apply a positive voltage between pins 2 and 3 of the OUTPUT ON-OFF
port (3, Figure 2-2) to turn the output ON (refer to Table 1-7 for detailed signal require-
ments).
4. At the front panel, E
o
MODE (23, Figure 2-1) and REMOTE OUTPUT ON-OFF (5) indica-
tors will be on.
