Supervisor Setup
6.9 Supervisor Setup
The Supervisor menu provides facilities for programming settings. These are made during
installation as follows:
6.9.1 Protective Vent
The protective vent can be enabled or disabled and causes the discharge of pressure at a
controlled rate if the measured pressure exceeds 110% full-scale. This protects the pressure
sensor from over-range.
The Power-up trapped pressure vent can be enabled or disabled from the protective vent menu.
6.9.2 In-Limits
A tolerance value can be set at the set-point. When the controller achieves the set-point, the
instrument controls within this set tolerance value. It does not affect controller stability or
precision. The instrument uses the ‘in-limits’ flag when performing a control task such as Leak
Test or Switch Test.
Note: In remote control, the control computer can be used to interrogate the ‘in-limits’ register to
confirm the controller has achieved set-point.
6.9.3 Alarms
An alarm can be set to trigger when the pressure exceeds the high alarm or falls below the low
alarm. A buzzer sounds when the alarm triggers and the alarm symbol (bell) appears on the
display.
6.9.4 Communications
Selects a communication port parameter. Simultaneous operation of the RS-232, IEEE 488 and
Ethernet interfaces is fitted as standard.
The user can select appropriate settings for communicating with the control computer (PC) and
the required command protocol. Refer to K0472, SCPI Remote Communications Manual or
K0469 Heritage Communications Manual.
6.9.4.1 RS-232
Located on the rear panel an external RS-232 connection has the following configuration:
INFORMATION A PIN protects the Supervisor menu against unauthorized
use. Each instrument on delivery contains the factory set PIN (0268). To continue
protecting the supervisor setup menu the PIN should be changed as soon as
possible.
