7. Press [F1]-[F4] to select the desired
Error Response
option, as described in
Table 1-6 below.
8. Press [F1] - [F4] to set up another output or press [EXIT] to select another slot for
set up.
1.7.3.2.2 Setting Up Alarms 1. Use the [F1]-[F3] keys to set up alarm relays A, B, or C, respectively.
Note:
The set up of alarm A is used as an example. Identical procedures would be
used to set up the other alarms.
2. Press [F1] = OFF to disable Alarm A and return to the previous prompt, or press
[F2] = HIGH, [F3] = LOW or [F4] = FAULT to specify the type for Alarm A.
3. Press [F1] = NO for standard operation or [F2] = YES for Failsafe operation.
4. Use the [
←
] and [
→
] and [F1]-[F4] keys to select a
Channel
option for the data
source.
5. The prompts now vary with your choice in step 2.
• If you selected FAULT, proceed to step 6.
• If you selected HIGH or LOW, complete the steps below.
a.
Use the
[
←
] and [
→
]
and
[F1]-[F4]
keys to specify the desired Output
Measurement parameter.
b. Enter a value for the trigger point of the alarm and press [ENT] .
6. To select the
Fault Type
that will trigger the alarm, press [F1] = FLOW, [F2] =
OTHER (non-flow), or [F3]= ALL.
7. Press [F1] - [F3] to set up another alarm or press [EXIT] to select another slot for
set up.
1.7.3.2.3 Setting Up
Totalizer/
Frequency Outputs
1. Press [F1]-[F4] to set up outputs A, B, C or D, respectively.
2. Press [F1] = OFF to disable output A and return to the previous prompt, or press
[F2] = FREQ or [F3] = TTLZR to designate output A as a frequency or a totalizer
output, respectively.
Note:
The setup of output A is used as an example. Identical procedures would be
used to set up the other outputs.
3. Use the [
←
] and [
→
] and [F1]-[F4] keys to select a
Channel
option for the data
source.
• To program a frequency output, go to step 4.
• To program a totalizer output, go to step 5.
1.7.3.2.4 Frequency Output 4. The FREQ output, [F2] , produces a frequency pulse that is proportional to the
output measurement. Complete the steps below to program the frequency
output.
a.
Use the
[
←
] and [
→
]
and
[F1]-[F4]
keys to specify the desired Output
Measurement parameter.
b. Enter the
Base
value for the low end of the frequency output range and press
[ENT] .
c. Enter the
Full
value for the high end of the frequency output range. Press
[ENT] .

Option Display Response
HOLD Holds the last “good” reading.
LOW Forces the outputs to the low set point.
HIGH Forces the outputs to the high set point.
OTHER Allows user to enter 4-20 mA error level in mA.
