20. Timed alarm #2
22. Periodically M51 Timer 23. Oct Not Using
The OCT circuit does not source voltage at its output. It must be connected with an
external power and pull-up resistant for some occasions.
When the OCT circuit is close, it will draw current. The maximum current shall not
be over 100mA.
Attention: the maximum voltage applied to OCT can not be over 80 volts.
Relay or OCT2 setup
By selecting a proper input source, the RELAY will close when the trigger event
occurs
The available trigger sources are:
0. No Signal
2. Not Ready(No*R) 3. Reverse Flow
5. FO Over 120%
8. Batch Control

22. Periodically M51 Timer 23. Disable Relay
The RELAY is of SPST (Single pole, single throw) type. It is rated for 110VAC max
and have a current rating of 0.5A resistive load.
It highly recommended that a salve relay to be utilized whenever a large resistive
load or inductive load is to be controlled.
Note. In order to make the user interface compatible with the former version7, the
name RELAY was used other than OCT2, but in fact it is an OCT output.
Window for selecting the trig signal for the built-in batch controller. Available trig
sources:
0. Key input
1. Serial port
2. AI3 rising edge
3. AI3 falling edge
4. AI4 rising edge
5. AI4 falling edge
6. AI5 rising edge
M80
7. AI5 falling edge
8.Timer periodically
9.Timer daily
For the input analog current signal, 0 mA indicates "0", 4mA or more indicates '1'.
By selecting item #8, the batch totalizer can be started periodically by the internal
timer located at Menu51. When the batch totalizer is full, a signal which indicate the
batch is full can be direct to either the OCT or the RELAY terminals to stop the
pump or other devices.
By selecting item #9, the batch totalizer could act as totalizer witch runs for only a
period of the day so that a alarm signal could be produced if the total flow during
that time period is over a certain amount of. For example, if you want a alarm signal
