Troubleshooting

Condition		Corrective Action
1	Unit does not have power	Check physical connection—Confirm internal cabling is not frayed or disconnected Check power supply LED indicators Check power supply load—Confirm the power load was properly calculated
2	Instrument was not auto-detected	Ensure instrument supports HART—If not HART supported, used generic configuration NOTE: The X5000/S5000 second sensor does not auto detect with HART and must be manually added as a generic sensor. Ensure instrument is properly wired
3	Buzzer is not working or is not loud enough	Ensure damper is not closed Ensure buzzer is properly wired
4	Channel does not appear to be showing proper reading	Ensure instrument is properly wired Ensure there are no faults with instrument Ensure input module is properly secured and connected to bus Ensure detectors are set in default analog settings NOTE: For X5000 and S5000 sensors, the 0 value is 4.04 mA so the readout at the SENTRY io might be slightly higher than 0 – this is normal operation.
5	Failed to recognize hardware	Ensure input module is properly secured and connected to bus
6	Touchscreen not responding	Ensure user is not wearing touch-resistent gloves Clean hands and clean screen
7	Relay not operating as expected	Ensure relay module is properly secured and connected to bus Ensure all preceding modules are properly secured and connected to bus Ensure relay condition is properly configured in relay assignments and cause & effect programming Ensure relay is properly wired for configuration Ensure relay is wetted, if required by application Ensure current is not below minimum requirement for relay Ensure relay configuration meets system specifications (example: less than 2 amps) Check for damaged equipment
8	Analog output is not working	Ensure wiring is properly installed to support desired configuration
9	Local transmitter settings do not match controller settings (example: set-points, scale, units)	Ensure controller settings match expected values for connected instruments On the Setpoints screen in the SmartStart configuration wizard, select Write A1 & A3 alarm set-points to MSA detectors via HART
10	Instrument reading does not match controller reading	Ensure instrument is properly wired Ensure instrument is properly configured Check instrument voltage Ensure detectors are set in default analog settings
11	Channel not reporting an alarm	Ensure instrument is properly wired Ensure alarm condition is properly configured in relay assignments and cause & effect programming Ensure local and controller set-points are configured as expected Ensure alarm condition is not inhibited
12	Discrete/Digital Input not working	Ensure input is not inhibited Ensure input is properly wired Ensure input is enabled Check local vs. SENTRY io setpoints
13	System time incorrect	Check settings Check NPT setting
14	Communication output not working	Check settings (IP address, etc) Check wiring/cableing
15	Forgotten/lost password	Call MSA
16	TagName is not correct	Check setting for instrument on channel
17	Manual Identification	Refer to detector for necessary manual identification information
18	Wrong instrument connected to channel	Check wiring Check proper instrument is connected to proper wire terminals
19	Sensor 2 not displayed for dual sensor transmitter (X5000 and S5000)	HART devices only report sensor 1. Use the generic setup to manually configure sensor 2.
20	Wrong user manual shown for channel	Check correct instrument is connected Check correct manual is uploaded
21	Change from 3 to 2 setpoints (or vice versa)	Check configuration and change, if needed
22	Discrete/digital input not latching	Check settings on controller NOTE: Once 3 alarm setpoint configuration is selected, 2 setpoint configuration is not allowed due to inadvertent changes to Cause & Effect and Voting. Changing to 2 setpoint configuration requires Reset Configuration.
23	Remote silence not working	Check wiring
24	Remote reset not working	Check wiring Check active alarms
25	Relay contact not powered	Most relays are dry—Check manual for wetting contact
26	View/export program logic	Check logic in cause & effect settings Export logic in cause & effect settings
27	Cannot configure "two relay voting" scheme	Create second voting scheme that uses same inputs with a different output
28	Not all channels displayed on dashboard	Change view configuration Follow arrow to next screen showing additional channels
29	Fault code on screen	Any fault code shown is derived from HART command 48. See instrument display for more information
30	Can I export trends	Copy file from SD card directory <dir>
31	Can I export cause & effect	Copy file from SD card directory <dir>
32	Oxygen Alarms can't write to detectors	Note that Alarm set-points for Oxygen sensors cannot be written to the detectors. This is because some Oxygen sensors utilize upward acting alarms and SENTRY io uses only downward acting alarms for Oxygen therefore this rule prevents inconsistencies in operation. Setpoints at these detectors need to be altered manually.
