6.7 Supervisor Set-up
The Supervisor menu provides facilities for programming settings. These are made during
installation as follows:
Important Note:
A PIN protects the Supervisor menu against unauthorised use. Each instrument on delivery
contains the factory set PIN (0268). To continue protecting the supervisor set-up menu the
PIN should be changed as soon as possible.
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.
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.
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.
Comms
Selects a communication port parameter. Simultaneous operation of both the RS232 and the
IEEE 488 interfaces is fitted as standard.
The user can select appropriate settings for communicating with the control computer (PC)
and the required command protocol. (Ref: K0472, SCPI Remote Communications Manual or
K0469 Heritage Communications Manual).
