NOTE

The actual 4-20 mA output can be read on the
UD10 display by navigating to:
Display Status > Debug Menu > Output Readback.
“Output Readback” is the actual 4-20 mA output
as read by the UD10.

Configuration protection
Upon completion of installation and commissioning, it is

required that the user password-protect the UD10 safety

related parameters that are accessible via the faceplate

display, HART, MODBUS, or Foundation Fieldbus in

order to prevent accidental or deliberate change of

configuration data during normal operation. To password

protect the UD10, the user must set the write-protect

function to “on” and enter an 8 character password.

The user will be required to disable write protect prior to

any future configuration changes, and must re-enable

write protect upon completion of these changes.

OpERATION, MAINTENANCE, INSpECTION AND
pROOF TESTING
All normal installation, start-up, and field calibration

recommendations as documented in the UD10

instruction manual are applicable to the Safety Certified

UD10 Universal Display.

Safety-Certified UD10 Universal Displays require

additional Proof testing to be performed in all cases.

Personnel performing Proof Test procedures shall be

competent to perform the task. All proof test results

must be recorded and analyzed. Any corrective actions

taken must be documented in the event that an error is

found in the safety functionality. The Proof tests must be

performed at a frequency as shown in Table 1.

WARNING

Failure to perform the specified testing and
inspection may lower or void the SIL rating for the
product or system.

vISUAL FIELD INSpECTION pROOF TEST
Tools Required: None

Visual inspection of Safety-Certified UD10 and

connected devices shall be conducted as needed

to confirm that no external blockage of path into the

sensing chamber/area exists, eg. debris, trash, snow,

mud, external equipment, etc. Corrective action shall

include removal of such impediments should they

exist. All devices monitored by the UD10 must be

inspected to ensure that they are capable of providing

expected performance and protection.

Completion of Visual Field Inspection Proof test must

be recorded and documented in the SIS logbook.

RESpONSE pROOF TEST
Tools Required: Compressed Calibration Gas Kit

provided by Det-Tronics, or other

device stimulation method

The Response Proof Test must be performed while the

UD10 and attached device are in NORMAL operation

and requires application of sufficient stimulation to put

the device into alarm state. The user must then inspect

the signal output level to ensure that the signal output

is accurately indicative of the applied condition.

WARNING

Any external alarm equipment, systems or
signaling devices that could be automatically
initiated by performing this test must be disabled
or bypassed before performing this test!
