SECTION 1: ROBOT SAFETY & RISK ASSESSMENT Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A technician is performing a routine teach pendant operation on an LR Mate 200iD
inside a fully enclosed work cell. The cell has a light curtain at the entry point, a safety
mat at the operator station, and a two-hand palm button for cycle start. During the teach
operation, the technician notices the robot continues to jog at 10% override even after
breaking the light curtain beam.
A. Continue the teach operation, because the light curtain is only required during
automatic mode
B. Immediately stop the operation and verify the light curtain is mapped to the proper
safety stop group in the DCS settings ✓ CORRECT
C. Reduce the override to 5% and continue, because lower speed compensates for the
safety device failure
D. Switch to T1 mode, because T1 mode automatically overrides all external safety
device faults
,Correct Answer: B
Rationale: A light curtain that fails to stop robot motion when breached indicates a
serious safety system fault, likely a misconfiguration in the Dual Check Safety (DCS)
stop group mapping, and operations must halt until the fault is resolved. Continuing at
reduced speed or switching modes does not address the underlying safety hazard that
could lead to personnel injury. FANUC DCS requires every safety device to be explicitly
mapped to a stop group; an unmapped device is effectively a nonfunctional device.
Question 2 of 50
A safety engineer is conducting a risk assessment for a new M-20iA material handling
cell where operators manually load parts into a fixture while the robot performs
pick-and-place in an adjacent zone. The engineer must determine the minimum required
safety integrity level for the system.
A. SIL 1 is sufficient, because material handling applications have inherently low risk
B. SIL 2 is required, because any human-robot collaboration demands at least this
integrity level
C. SIL 3 is required, because the presence of operators in the work envelope during
robot operation creates high risk ✓ CORRECT
D. SIL 4 is required, because all industrial robot systems must meet the highest safety
integrity level
Correct Answer: C
Rationale: When operators are present within the robot work envelope during automatic
operation, the risk of serious injury is high, and SIL 3 is the minimum required integrity
level to ensure adequate risk reduction through safety-rated monitored stops and
protective measures. SIL 1 and SIL 2 do not provide sufficient risk reduction for
collaborative or adjacent manual operations, and SIL 4 is reserved for nuclear or
aerospace applications where catastrophic failure is unacceptable. ISO 10218-2 and
ISO/TS 15066 provide the framework for determining SIL requirements based on
severity, exposure, and avoidance probability.
,Question 3 of 50
A maintenance team is replacing a failed servo motor on an R-2000iC. The robot is
powered down, the main breaker is locked out, and the team has verified zero energy
with a multimeter. Before beginning disassembly, the lead technician notices residual
pressure in the pneumatic gripper line.
A. Proceed with motor replacement, because pneumatic pressure is unrelated to
electrical servo work
B. Bleed the pneumatic system and verify zero pressure before continuing, because
stored energy in any form must be eliminated ✓ CORRECT
C. Disconnect only the electrical connector to the gripper solenoid, because isolating
the electrical control removes the hazard
D. Place a warning sign on the pneumatic regulator and proceed, because residual
pressure is minimal and poses no risk
Correct Answer: B
Rationale: Stored energy in pneumatic, hydraulic, or spring systems must be fully
dissipated before maintenance begins, because unexpected actuator movement from
residual pressure can cause crushing or pinching injuries during close-proximity work.
Isolating electrical control does not eliminate mechanical energy, and warning signs do
not physically prevent energy release. OSHA lockout/tagout standards and FANUC
maintenance procedures require verification of zero energy state across all energy
sources, not just electrical.
Question 4 of 50
An operator enters a collaborative work cell to clear a part jam from an M-10iD gripper
while the robot is in automatic mode. The robot is equipped with a safety-rated
monitored stop function. The operator reaches into the work envelope without pressing
the deadman switch.
, A. The robot should continue its programmed cycle at reduced speed, because
collaborative robots are designed for human proximity
B. The robot should execute a safety-rated monitored stop, because the presence of a
human in the work envelope must trigger a protective stop ✓ CORRECT
C. The robot should switch to T1 mode automatically, because any human entry
defaults the system to teach mode
D. The robot should sound an alarm but continue operation, because the operator is
responsible for avoiding the robot path
Correct Answer: B
Rationale: A safety-rated monitored stop is the required protective measure when a
human enters the collaborative workspace during automatic operation, ensuring the
robot halts and maintains position monitoring until the hazard is cleared. Continuing
operation or switching to T1 mode without explicit mode selection violates ISO/TS
15066 collaborative robot safety requirements. Collaborative applications depend on
reliable safety-rated stops; any failure to stop on human presence is a critical safety
fault that must trigger immediate system shutdown.
Question 5 of 50
A plant manager is configuring the safety parameters for a new ARC Mate 100iD
welding cell. The robot will operate at full speed in automatic mode behind fixed
guarding, but operators must access the cell for tip dressing and wire spool changes.
The manager must select the appropriate robot operating mode for maintenance
access.
A. Automatic mode with the override set to 50%, because reduced speed allows safe
maintenance access
B. T1 mode with the deadman switch engaged, because T1 limits speed to 250 mm/s
and requires constant operator presence ✓ CORRECT
C. T2 mode with the cycle start button, because T2 allows full-speed program
verification during maintenance
