5.5.8 Special commissioning requirements
5.5.8.1 SUBSYSTEM MMI’S
Doc No. SALT1700AS0001 Issue A
TCS Specification
The TCS shall support the running of subsystem MMI GUI’s on the SO and SA workstations.
5.5.8.2 TEST POINTS
Means shall be provided to measure electrical signals and interpret data transferred between
subsystems and major electronic items within each subsystem.
5.5.8.3 TEST DATA
Each subsystem shall send to the TCS (Event Logger) the values of all internal variables that
may need to be interrogated during commissioning and testing, but would not normally be
needed for telescope control by the TCS. Details will be provided in the SALT Electrical Interface
Control Dossier.
5.5.9 Software
Each subsystem shall comply to the requirements defined in SALT Software Standard referred to
in Section 2.
5.5.10 Computer Hardware
Each subsystem shall comply to the requirements defined in SALT Computer Standard referred to
in Section 2.
5.5.11 Electrical Design
5.5.11.1 UPS
5.5.11.1.1 Installed Capacity
The UPS will provide power to the TCS computers for at least 20 min during a power failure.
5.5.11.1.2 UPS monitoring
The TCS shall monitor the UPS in the following way:
• The battery charge level and overall health, with operator warnings as appropriate.
• A “normal power-fail” signal to indicate the loss of normal power so that contingency
software can be activated (if applicable)
• A “UPS power-fail” signal to warn the operator to shut-down critical software processes
5.5.11.2 STANDBY POWER GENERATORS
5.5.11.2.1 Installed Capacity
The installed emergency power generation capacity will be adequate to allow normal
operation of SALT during a power failure. Non-essential power users may be turned off.
5.5.11.2.2 TCS operation upon power failure
