SIL Certified Safety Manual for Enhanced Model 705-51AX-XXX

For this reason, the Model 705 transmitter has a timeout
feature in which, after 5 minutes with no key presses, the
transmitter will revert back to the scrolling default screen
and a password must be used to make any additional
parameter changes.

NOTE: HART interface shall be interference free assuming the end

user only allows access to HART communication to trained
personnel who may not make any changes to the device
parameters while the device is operational in the SIF.

Site Acceptance Testing

After installation and configuration is complete, a site
acceptance test should be performed to ensure proper opera-
tion. This procedure is identical to the Proof Test Procedure
described in Section 6.1.4 of this manual.

Record the results for future reference. It is also recom-
mended to document the existing transmitter configuration.
Configuration Data Sheets, included at the end of the
I & O Manual 57-600, can be used for this purpose.

5.8.1 Diagnostics and Response Times

Continuous internal diagnostics are present within the
Enhanced ECLIPSE Model 705 transmitter. In the event a
Fault is detected, a message will appear on the LCD and the
output current will be driven to 3.6 mA or 22mA depending
on how the FAULT parameter is configured.

A) Start-up Time:

a. From application of power to normal operat-

ing mode: 4 seconds

b. From application of power to Fault mode:

29 seconds or less (Assuming a Fault is present
upon start-up)

B) Safety Response Time: 16 seconds

a. This is defined as the time from the normal

operating mode to the Fault mode upon the
occurrence of a fault.
