SET
enclosure supply has been ordered, the compliance
voltage is 24-26 VDC. If the user chooses to supply
power a 24-30 Volt regulated DC source should be
employed. It is connected to pins 7&14 (+) and 6&13
(-) in P3 on the rear panel of the enclosure, see
connector diagram in Section 2-1.4.1. Compliance
voltage will be 2-4 Volts less than the supply voltage.
Output of the external supply must be fused at 1A o
lower.
Current (I) is set by a resistor, R
set
.When using
constant current, jumper W(3) must be installed
connecting the (-) power input to excitation common.
This jumper is installed at the factory.
The value supplied gives approximately 6 mA. It may
be changed to provide currents over the range of 1 to
20 mA using the following formula:
R
set
= 1250/I (in mA)
In the tables that follow component designations are
supplied for R
set
and the jumpers that connect
excitation to the input signal lines. These jumpers
must be removed (placed in their storage position) fo
all transducers other than ICP/EIS types.
Jumper J1 connects –In to excitation common and J2
connect the constant current power to +In. J1 and J2
are related to physical jumpers (W numbers) for each
channel by the following table. The factory
configuration is for ICP/IES transducers.
Important: AC coupling must be used with
current excitation that uses the signal inputs
to deliver power to the transducer. It blocks
the DC voltage on the input that would
otherwise overload the amplifier input.
