Alarms configuration (flash, colour and relays)
The display allows the user to program 2 alarms that can be used by the flash, colour and
relays functions. The trigger of the alarm can be delayed with a timer or by a hysteresis value. The
activation of the alarm may be programmed so that it acts above or below the programmed setpoint.
The displays with the relay output option may generate control and alarm signals for their use
by other units. The Flash function allows the digits to flash if one of the relays is activated.
The equipment that has the colour option may be programmed to display the value using
colour red, green or yellow.
In displays with colour option, alarms may change the digits colours: Red, green or yellow.
The configuration of the alarms is accessed by two ways:
If the display has colour or relays option, the alarm configuration is accessed through the
parameter rLS. Otherwise, it is accessed through the parameter FLH.
