Introduction

This document collects the procedures performed to verify the correct function of the Global Interlock System (GIS), which ensures the protection of the different systems of the telescope.

It includes the steps followed to complete GIS tests. Passing the tests confirms the correct communication, reception and emission of signals, between the different safety systems and, summarizing, the correct actuation of the system.

Technical description

Architecture:

The safety interlock system of the telescope, named Global Interlock System (GIS) hereafter, is a distributed arrangement where a central safety controller is connected to all subsystem controllers (M1M3, TMA, Dome, etc.), by means of safety networks.

LASER, M2, PFLOW and AcFiEa subsystem controllers are directly connected to the central safety controller. Those subsystems compose the central controller's periphery.

Testing architecture:

The architecture described below is the structure where the actuation of the Global Interlock System (GIS) is tested.

LASER, M2, PFLOW and AcFiEa subsystem controllers are hardwired to distributed I/O modules. Those modules are connected to the central controller by means of safety networks.

Hence, GIS and GIS's periphery are tested in a real architecture situation.

M1M3, TMA, AUX_Tel and DOME are systems with a dedicated safety controller. Those systems are connected to the central controller M1M3 and TMA, but AUX_TEL and DOME are not ready, in any case are not the subject of these tests at the level of inputs and outputs, but yes at the level of causes and effects. When they are all installed and with their operating program, additional tests will be carried out to check that the communication between them is correct. For the moment these signals will be forced from the PAS4000 to verify the security matrix.

Detections, relays and signals related with LASER, M2, PFLOW and AcFiEa systems are reproduced physically with ETPBs and LEDs, as it is shown in Fig. 1.

In some cases, they are already connected to the corresponding I/Os, so they have been disconnected from the keypad, eliminating their function.

Testing procedure

Tests are performed in the installations of the Rubin Observatory, for Franco Colleoni y Francisco Javier López, with the procedure described in the document 7186-GIS_TestSystem.pdf.

Detections and relays will be checked individually, one by one. Also, the Detection that can be delayed will be check independently.

First, detections will be tested one by one, afterwards, relays and, finally, the delays. Detailed procedure with every step is presented in the following sections.

Detections and relay forcing method depends on the system to which belong:

  • Signals from the external controller, M1M3, TMA, AUX_Tel and DOME systems, are forced via software.

  • The rest of the signals, from LASER, M2, PFLOW and AcFiEa, are forced by pressing the corresponding ETPB or I/O if it is connected to the sensors/actuators.

Detection' signals are check in UI and via software.

Relay signals are check in the UI. Relay signals can activate Detections, hence, the corresponding Actions are activated.

The Actions associated with those inputs will be checked observing signals (in HMI or in the software) and, in case there is a LED associated with the signal involved, observing the state of that LED.

  • Action signals to the external controller, "testing controller", are checked in HMI and via software.

  • Action signals to the Central Controller are checked in HMI and in the corresponding LEDs.

ITEM FORCING METHOD CHECKING METHOD
Detection

-M1M3, TMA, AUX_TEL and DOME systems: Forcing signal in test Controller.

-Other systems: Pressing ETPB when is not connected.

 UI and software.
Relay

-M1M3, TMA, AUX_TEL and DOME systems: Forcing signal in test Controller.

-Other systems: Pressing ETPB when is not connected.

Relay state in UI.

Detection (and corresponding Actions) originated by the relay in UI and software.
Action

Cannot be forced by itself.

When a detection that originates the release of the action is active, the action signal is activated.

-M1M3, TMA, AUX_TEL and DOME systems: LED, UI and software.

-Other systems: UI and software.
Reset By pressing RESET button in the UI.

-M1M3, TMA, AUX_TEL and DOME systems: LED, UI and software.

-Other systems: UI and software.

Table 1 Signals forcing and checking method.

AUX wasn't tested, as AuxTel IS is not installed yet. Anyway, GIS will only send the Earthquake signal.

Detections testing

This part will be performed with a user logged in with administrator permissions, Level 4 of user management. User levels is described in the document GIS User Interface Manual, (Ref: 5).

Delays testing

Delays postpone a certain time (configurable) the actuations related with a specific event.

This part will be performed with a user logged in with administrator permissions, Level 4 of user management. User levels is described in the document GIS User Interface Manual, (Ref: 5).

Earthquake delay

Earthquake delay postpones a configurable time the actions related with the event D-2 Catastrophic Earthquake Interlock.

D-2 event activates the following actuation signals:

  • A-3 TMA Discharge Capacitor Banks

  • A-4 TMA Disables other equipment

  • A-5 TMA main drives- STO and engage the brakes

  • A-6 Camera cable wrap drives STO

  • A-7 Dome shutter doors and Windscreen Drives -Disable

  • A-9 Dome Louvers and Dome Locking Pin -- Disable

  • A-10 Dome Rear Doors Drives -- Disable

  • A-11 Dome Azimuth Drives -- Disable

  • A-12 STO M2 Hexapod

  • A-13 STO M2 Actuators

  • A-15 STO Camera Hexapod

  • A-16 Pflow Platform Lift -- Disable

  • A-18 M1M3 Support System (Earthquake stop)

User permissions check

Tests described below (in sections [5]{.underline}, [6]{.underline} and [7]{.underline}) are performed with a user logged in with administrator permissions. Now, the following tests are performed in order to verify that each user has access to the defined actions in the document GIS User Interface Manual, (Ref: 5).

Level 3 permissions check

Identification to be tested: Checked Responsible
No user is logged in.
    ✔
Franco Colleoni
Log in with a user with Level 3 permissions.
    ✔
Franco Colleoni
Name of the user logged in is shown in the screen.
    ✔
Franco Colleoni
Check that button “RESET” appears on the screens that correspond.
    ✔
Franco Colleoni
Log out.
    ✔

Franco Colleoni
Name of the user logged in is shown in the screen.
    ✔
Franco Colleoni
Check that button “BYPASS” does NOT appear in any screen.
    ✔
Franco Colleoni

User Interface

During the tests, the user interface was being handled and some problems were detected, such as:

  • For the Dome page, in the Detections the label for D11 and D12 are swapped.

  • The date and time of the UI are not correct

  • Sometimes the HMI stops working properly, freezes or resets, displaying a low memory message. This does not affect the actual interlocks, only their representation on the screen.

The first two problems have been solved after the completion of the tests. But the third one has not been solved and the consultation has been transferred to the team's supplier, Pilz, so this last point is still pending.
