Each operating unit with Operator privileges can disable the Operator privi-
leges for other operating units/control stations (lock). In this case, no other
operating unit/control station can obtain Operator privileges and it therefore
remains a Viewer.
Locking of the Operator privileges in Command Touch:
n
User privileges in addition to the Operator privileges and Viewer
privileges are specifically available only in the Command Touch (see
Command Touch operating manual).
If user privileges have been assigned/restricted via the Command oper-
ating unit (in the User configuration menu), all other operating units
or the control station/PC become the viewer. Neither other operating
units nor the control station can obtain Operator privileges. If an
attempt is made to obtain Operator privileges, a message appears.
If a Command with restricted user privileges is disconnected from the
constant temperature equipment, an error message is generated and the
constant temperature equipment stops. The user must switch the device
off and on again. The Master operating unit automatically becomes the
Operator.
Locking of the Operator privileges in the control station
n
If the monitoring of the control station is active, the Operator privileges
are locked/owned exclusively by the control station.
No operating units can obtain Operator privileges. If an attempt is made
to obtain Operator privileges, a message appears.
If the control station drops out, the constant temperature equipment is
switched off and switched on again, an alarm is triggered or the control
station monitoring is deactivated. Exclusive ownership is withdrawn from
the control station.
