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 o
t
her than OCT2, but in fact it is an OCT out

Window for selecting the trig signal for the built-in batch controller. Available trig
sources:
0. Key input (press ENT key to start the batch controller)
1. Serial port
2. AI3 rising edge (when AI3 receives 2mA or more current)
3. AI3 falling edge (when AI3 stop receiving 2mA or more current)
4. AI4 rising edge (when AI3 receives 2mA or more current)
5. AI4 falling edge (when AI3 stop receiving 2mA or more current)
6. AI5 rising edge (when AI3 receives 2mA or more current)
7. AI5 falling edge (when AI3 stop receiving 2mA or more current)
8.Timer periodically (define the start time and interval time in M51)
9.Timer daily (define the start time and interval time in M51)
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 which stand for the
total flow is over 100 cubic meters during the period of every day from 20:00 to 06:00,
setups is like
M51 start time =20:00:00
M51 interval =10:00:00
M51 log times =9999 (means always)
