6.4. Switches
Switches (e.g. level switches) may be connected only to the digital inputs (IN1 to IN8) (IN9 - IN16,
when circuit board cb-8in (1) present, IN17 - IN24, when circuit board cb-8in (2) present).
Furthermore, a number of switches can be determined, for each process step.
In the case of the switches, the input this is
connected to also has to be entered in the
inventory.
Whether the switch “is "normally closed
(NC)" or "normally open (NO)" also has to be
entered.
Example for a “Exceeded pressure” switch.
All switches have other settings on top of the i
nventory settings, such as a delay on the monitoring.
An examination is made in following sections of what the function of the switches is, how the controller
will react and what settings are available.
If a monitoring on a switch is switched on during a process the process will be controlled during this
time and if the switch is still active after a delay (that can be set) the unit is switched off. The exception
to this is the “Alarm reset” switch. This does not affect the process but only the alarms.
Attention!
The switches in the storage tank (high and low level) are not covered here. These correspond to the
“Storage tank" component.
6.4.1. Exceeded pressure
The “Exceeded pressure” switch may be placed at a position where an overpressure has to be
controlled.
If the unit is switched off after an
overpressure situation these can only be
switched on again manually.
For information about the inventory see § 6.4
“Switches” on page 23.
A further delay may be entered (0-9999 seconds) for the monitoring.
