Chemglass CG-16000 - Manual (Page 2)

AUX INPUT CHANNEL 1:
The AUX input is programmed to be
used for a vacuum/pressure transducer
input, but may be used for any other
auxiliary input device. Pins 2 and 4 are
supplied with 24VDC. Note, some models
may not include the optional internal 24VDC power supply. Therefore requiring an
external power supply for the input device. The input signal is applied though pins 1
and 3. The maximum input signal cannot exceed ± 60VDC. If using an analog 4-20mA
input signal a 250
Ω shunt resistor must be placed across Pins 1 and 3. Also, the
Span_U value will need to be changed to 5 and the Range set to 6V.
The Span is the minimum (lower) and maximum (upper) voltage
input signal measured values. The Range value must be set so that
it is slightly larger than the upper span voltage value. These values
are preset, so the closest greater value must be selected. Refer to
the Yokagawa manuals for more detail on setting the Scaling
parameters. Shown are the settings which are pre-programmed
with the Data Logger. A 4 pole Male Nano connector is required for
connection.To change parameters consult the Yokagawa Users
Manual.

RPM INPUT CHANNEL 2:
The RPM input is programmed to be
used with the Chemglass DC 1/8HP Motor
Controller or any device that outputs 0-
10VDC. Note, when using the Chemglass
1/4HP DC motor Scale_U must be set to
500. If using an analog 4-20mA input
signal a 250
Ω shunt resistor must be placed across Pins 1 and 3. Also, the Span_U
value will need to be changed to 5 and the Range set to 6V. The
Span is the minimum (lower) and maximum (upper) voltage input
signal measured values. The Range value must be set so that it is
slightly larger than the upper span voltage value. These values are
preset, so the closest greater value must be selected. Refer to the
