Modes Of Operation - Baker Hughes Masoneilan SVI II ESD Quick Start Manual

Hardware Configuration Lock
Additional security is achieved using the hardware configuration-lock jumper shown in Figure 15
on page 49. When set to the secure position, configuration and calibration are not permitted by
the local interface or by remote communications. Pushbuttons, ValVue ESD and handheld are
locked out, except to examine configuration, calibration, and position. This is similar to Security
Level 1 shown in Table 7 on page 58.

Modes of Operation

To run setup and calibration the SVI II ESD must be in the correct operating mode. The SVI II ESD
has three modes of operation:

mode, since the device needs to be configured.

The SVI II ESD goes to the failsafe state whenever the safety function is triggered or if one of the
critical faults (checksum errors, stack errors, Factory Write Latched Event, or MCU Internal Mal-
function - see Critical status tab in online help) occurs. When tripped, Tripped appears on the LCD,
as well as on the ValVue ESD's software interface. The trip occurs irrespective of the mode that
the SVI II ESD is in at that moment
If the LATCH function is enabled, LATCHED appears on the display when tripped. To reset the latch
