Limit relay values
Limit relay values can be configured for high/low limit levels. For both types of limits the function can be
activated/deactivated, and the limit relay can be named with a label used as text in an alarm list and in SMS
alerting.
Values can be set to which level the high/low limit relays are activated, and a delay can be attached, so that
a limit value must be exceeded for a given time before the signal is registered as active. It is possible to
choose whether to send the signal as an alarm or to act as a local alarm.
If an alarm (True overflow in progress) is desired, regarding the use of GEKKO for stormflow registrations,
the limit value is set with the same value as the value for the overflow edge. Furthermore, checkmark the
options
"High limit relay in use"
and in
"Alarm at high limit in use".
Digital Input (I1-I4)
I1-2 input on the GEKKO logger can be used as either standard 0-10 V inputs, or standard DI where "0" <5V
and "1"> 12V.
DI3-4 is either standard DI where "0" <5V and "1"> 12V or pulse inputs.
The input functions can be set in AcowaZoo when I1-4 is
selected in the Settings selection. VI1-2 contains the
following settings:
