Chapter4 BASIC OPERATIONS
This chapter describes the basic operations of SafetyOne. Make proper use of the
SafetyOne by thoroughly familiarizing yourself with basic operations and functions.
Internal states
The SafetyOne operates in five internal states, as shown in Table 4.1.
The LED display and output status for each state are shown in Table 4.2.1and 4.2.2.
Table 4.1 Internal states
State Description
Initial
Initial processing is performed immediately after power is supplied to the SafetyOne.
The internal circuits are checked and the LEDs show operation confirmation (blinking)
for 6 seconds (approx)..
Run
The SafetyOne is under normal operation. Logic processing continues without failures
or wiring errors. (Refer to "Chapter 5 LOGIC" for details.)
Configuration
A logic or OFF-delay timer value is being configured.
Configuration enables the logic and OFF-delay timer value. When completed, the
SafetyOne changes to the Run state. (Refer to "Logic configuration" and "Timer
configuration" in this chapter for details.)
Protection
An input monitor error has occurred with dual channel input, EDM input, or muting
input. When the problem is removed, the SafetyOne changes to Run state. (Refer to
"Canceling the Protection state" in this chapter for details.)
Stop
A failure or error has occurred with an external device or internal circuit. When the
problem is removed and the power is turned on, Stop state is cleared. (Refer to
"Canceling the Stop state" in this chapter for details.)
