Description
Core Product Summary (Brand / Model / Key Attributes)
The HIMA F7131 (order code 981713102) is a power supply monitoring module for classic HIMA planar safety systems (primarily H51q). It continuously supervises the 5 V system voltage generated by up to three power supplies and provides both visual and diagnostic status information.
The module features three front-panel LEDs, three test bits for the central modules, and optional 24 V monitoring outputs when used with the B9361 assembly kit. It includes buffer batteries to maintain monitoring capability during short power interruptions.

Detailed Product Overview
The F7131 is a dedicated monitoring module that supervises the critical 5 V logic supply in HIMA H51q and related planar systems. It can monitor the output of up to three power supply modules simultaneously.
Status is indicated by three LEDs on the front panel, giving immediate visual feedback of power supply health. In addition, the module provides three test bits that can be read by the central modules F8650 or F8651. These bits are available both for the system diagnostic display and for use inside the application program, allowing the safety logic to react to power-supply anomalies.
When the system is equipped with the optional additional power supply assembly kit B9361, the F7131 can also monitor the individual power supply modules via three dedicated 24 V outputs (PS1, PS2, PS3).
The module contains buffer batteries (type CR-1/2 AA-CB) that maintain the monitoring function during brief supply interruptions. HIMA recommends replacing these batteries every four years.
The F7131 occupies 4 TE of rack space and has very low power consumption (25 mA from the 5 V rail and 20 mA from the 24 V rail).

Dimensions, Mounting & Connection Notes
The F7131 is a plug-in module requiring 4 TE in the HIMA rack. It connects to the backplane for power and diagnostic signals. When the B9361 assembly kit is used, additional wiring is required for the three 24 V monitoring outputs. Battery replacement is performed according to HIMA maintenance procedures. Always follow the official installation guidelines for correct seating and earthing.
FAQ

Verification & Troubleshooting Notes
Check that the three front-panel LEDs correctly reflect the status of the monitored power supplies. Verify that the three test bits are correctly interpreted by the central module and, if used, by the application program.
Confirm battery age and replace the CR-1/2 AA-CB cells if they are older than four years. When the B9361 kit is installed, ensure the PS1–PS3 outputs are correctly wired and that the monitored power supplies are functioning. Refer to the official HIMA documentation for the complete connection details and diagnostic bit assignments of the F7131.
