The OK-relay in the User-terminal dialogue:
♦ In the dialogue there are one parameter for the OK-relay:
◊ Reset
♦ The parameter <Reset> in the dialogue will reset the latching OK-relay
after a fault has occurred, on condition the fault no longer exists.
♦ A further possibility for resetting the OK-relay is the parameter
<Confirm> in the dialogue in the block USER MENUS. This parameter
has the option <Reset all>. The OK-relay will also be reset with this
option.
♦ In addition the central OK-relay can also be reset remotely using a
push-button connected to the Reset input on the Base module (X22).
♦ When the monitoring function of the system is switched off (USER
MENU – Monitoring), an OK fault will be reset, but the OK-relay will only
be switched back to the fault-free status when the monitoring function is
activated once more.
8.3.2 Channel over-ranging identification function
Each A/D converter channel is permanently monitored for over-ranging.
Should it detect an over-range condition at an input channel, this is signalled
by the red LED on the input module (sensor interface or BCU CON module).
Furthermore a corresponding entry is recorded in the logbook.
8.3.3 LED signal at a relay module
♦ As a rule a relay output signal is:directly controlled from a Monitor block.
If this occurs the LED at the relay output module is used to signal the
monitoring status and relay status. Each relay output has 2 LEDs for this
purpose, a green LED and a two-colour (red and yellow) LED.
♦ The LEDs at the relay module signal two bits of information:
◊ Functional status of the associated relay output
◊ Announcement status of the preceding Monitor block (Logic block)
