SOFTWARE CONFIGURATION
Units are fully reprogrammable via our user-friendly Windows
95
or NT
IntelliPack Configuration Program (Model 5030-881).
A cable (5030-902) and converter (5030-913) are required to
complete the interface (Software Interface Package 800C-SIP).
See Drawing 4501-643.
The following transmitter and alarm attributes are selectable
via the IntelliPack Configuration Software. Refer to the
IntelliPack Transmitter Configuration Manual (8500-570) for a
detailed explanation of these attributes and their application.
Input Configuration
Input - Range:
This transmitter can be configured to accept
any one of the input frequency range types described in
the Input Specifications, or as an event counter, using the
IntelliPack Configuration Program.
Input - Samples (For Averaging Frequency Inputs Only):
Input averaging can be set to 1 (default), 2, 4, 8, or 16.
The value selected indicates the number of input signal
acquisitions used in computing a running average. This
is useful in helping to filter out transients. Note the
response time will be increased by the factor selected.
Input - Resistor (Pullup/Pulldown):
Utilize the optional on-
board pullup or pulldown circuits according to the input
type.
Input - Threshold (Bipolar/Unipolar):
Select either bipolar
(zero crossing), or unipolar (non-zero crossing) input
signal types. Two levels of input threshold and hysteresis
are available for each input type.
Event Counter - Debounce (0-1000ms):
0 (disabled) to 1
second, configurable in 5ms increments. You must
select appropriately with respect to input signal
bandwidth and characteristics. Used to eliminate
counting false pulses due to electro-mechanical relay
contact bounce and other mechanical effects.
Event Counter - Edge (Rising/Falling):
Select either the
rising edge (positive), or falling edge (negative) of the
input pulses to be counted.
Event Counter - Termination (Wrap, Auto-Reset, Latch):
Select none (wrap), auto-reset, or latching. None will
cause the counter to wrap around to zero from 65535.
Auto-reset will cause the counter to be automatically
reset to 0 when the value scaled to 100% is reached.
Latching will cause the counter to latch at the value
scaled to 100%. Any counter can be reset to zero at any
time by applying an active low counter reset signal to the
CRST terminal, or by clicking on the “Reset Counter”
button of the IntelliPack Configuration Software.
Excitation Voltage:
Use is optional. Select 8.2V or
+12V DC. Internally limited to 24mA, typical. Available
at the EXC+ and EXC- terminals of the module.
Input Calibration
: The configuration software can be used
to calibrate the input timing of this module.
Analog Output Configuration
Output - Range:
Unit can be configured for either a voltage
or current output range. A jumper must also be installed
between the output “I+” and “JMP” terminals for voltage
output (remove this jumper for current output).
Voltage (Jumper Required):
0 to 10V DC, 0 to 5V DC
Current:
0 to 20mA DC, 4 to 20mA DC, or 0 to 1mA DC
Output - Mode:
Select a normal acting (ascending), or
reverse acting (descending) output response.
Output Calibration
: The configuration software can be used
to calibrate the output conditioning circuit of this module.
Transmitter Configuration
Scaling:
Enter an input value for 0% output and an input
value for 100% output (these are also field adjustable).
Scaling is performed after averaging and converts the
engineering units of the input range (or a portion of the
input range) to 0 to 100%. That is, scaling allows virtually
any part of the selected input range to be scaled to 0%
and 100% at the output. For event counters, the input
value for 100% output is the maximum count value.
Minimum Input Spans:
10% of the selected input frequency
range. For pulse/event counting inputs, no minimum is
imposed, but 1000 pulses is recommended to maintain
reasonable output resolution.
Transmitter Computation Function
: This model provides
proportional computation only and no optional
computations are provided. Each input sample is
converted into a directly proportional output update.
End Points Configuration:
Transmitter: Zero/Full-Scale
Input maps to Zero/Full-Scale Output. Event counters
always have a count of 0 as the “zero” input and the
maximum count as the input for 100% output.
Alarm Configuration (Model 841T-1500)
The model 841T-1500 may be configured for simple limit
alarms. You may also refer to the IntelliPack 800A alarm
family for dedicated alarm modules that support other
operating functions.
Limit Alarm - Input:
The input signal range to the alarm is
the full range for the configured input type, irregardless of
the scaled range. For example, if the 0 to 100.00Hz input
range was selected using the configuration program, the
alarm can be programmed to any setpoint from 0 to
100Hz. If input averaging is used (samples > 1), then the
averaged input value will be used by the alarm.
Limit Alarm - Mode:
Select a High limit or Low limit for the
limit alarm function of this model. In this mode, the relay
will enter the alarm state when either the user-defined
high or low setpoint is exceeded for the specified amount
of time (this allows input transients to be filtered). Relay
remains in the alarm state until the input signal has
retreated past the defined setpoint, plus any deadband
(frequency inputs only), for the specified amount of time.
A high limit is assumed for the event counter input.
Limit Alarm - Setpoint:
A high or low setpoint may be
assigned to the relay and is programmable over the
entire input range (this is also field adjustable). The relay
will trip on an increasing input signal for a high setpoint,
and on a decreasing input signal for a low setpoint. A
high setpoint is assumed for the event counter input.
