17.2 Automatic resets:
It is possible to configure automatic resets for protection alarms. In the reset menu (1.4.4) it is possible to configure the Number of reset attempts
(1.4.4.1), the intervals between attempts and a period within which attempts will be made.
If the number of attempts is set to the minimum ‘’Off’’ value, the reset must be manual only. If the maximum value ‘’Always’’ is set, the RCK-862 plus
does not limit the number of reset attempts, it only respects the times.
If the value is set between 1 and 10, this number of attempts will be made within the configured reset period (1.4.4.3) and after this number of
attempts, a manual reset should be made.
With each occurrence of protection alarms, it will be checked how many alarms of the same type occurred within the configured period. If it is higher than
the configured value, the pressure switch will be blocked in alarm condition and a manual reset via Sitrad or via the interface in the control menu option
Reset will be necessary.
If the reset period has elapsed and the number of configured attempts has not occurred, the attempt counter will be reset.
17.3 Output signaling
It is possible to configure up to 6 digital alarm outputs through menu 1.4.5. Each output, when configured, will actuate together with the visual alarm.
The activation mode of this alarm output can be switched on or cycling.
!
In the event of a protection alarm, it will be checked if 3 other alarms of the same
type have occurred within the last hour, if so, the pressure switch will be blocked, if
not, it will be reset after 5 minutes.
In the event of a protection alarm, the pressure switch will be reset after 5 minutes
without limit of attempts and the setting of the reset period is indifferent.
Example 1:
Number of attempts = 3
Retry interval = 5 minutes
Reset period = 1 hour
Example 2:
Number of attempts = always
Retry interval = 5 minutes
Reset period = 1 hour
In the event of an alarm for suction pressure switch 1, digital output 5 will cycle with
Ton and Toff = 5 seconds.
And it will be turned off after leaving the alarm condition, or after the reset.
In the event of a low-pressure alarm on suction 1, output 6 will be activated until
manual or automatic reset is carried out.
Example: Configuring an output through the menu 1.4.5.1.
Example: Configuring an output via the menu 1.4.5.2.
Digital output = O5 (digital output 5)
Digital output = O6 (digital output 6)
Pressure switch: Suction 1
Pressure switch: Suction 1
Time on: 5 seconds
Time on: 0 seconds
Output function: Low pressure
Output function: Low pressure
Time off: 5 seconds
Time off: 0 seconds

Attention: As a factory default, the suction and discharge alarms are disabled and for their use it is necessary to configure an
appropriate limit depending on the application.
