1.4.3.4 OK-relay: X21 – Signalling of system interruptions
The OK-relay signals system events from the VIBROCONTROL 6000 Compact
monitor
(“OK” and “not OK”).
The potential-free contact of the OK-relay can be used to provide a signal to
peripheral electronic equipment.
Connection

OK - RELAY
Contact pin layout in normally-energised mode
Pin 1 ARM Arm of the OK-relay
Pin 2 NC Normally-closed contact
(normally-energised status)
Pin 3 NO Normally-open contact
(normally-energised status)
Note:
A list of possible reasons for initiation of an OK fault is contained in section D
in the chapter on Instrument Operation. The Logbook function, which simul-
taneously records all events that occur, is described in the same chapter.
1.4.3.5 Remote reset: X22 – Binary input for a global reset
The Remote reset connection serves for a global reset of a
VIBROCONTROL 6000 Compact monitor by a binary signal. All events are
reset and all sensor OK faults and relays in the latching mode will be reset.
The Remote reset is activated when pins 1 and 2 of the connection X22 are
briefly short-circuited; e.g. by a push-button or a bridge.
A bridge can permanently connect the terminals. The Reset function then
operates when the bridge is opened and then closed again (edge-triggered).

Note:
Limit setpoint violations that still exist will not be reset by the Remote reset.
An existing limit setpoint violation will automatically be signalled again.
