Chapter 4 Configuration
DI and DIS Safety Relays
The DI and DIS safety relays have a 10-position switch and use only the first nine positions. As
shown in Table 7, this switch configures the safety relay for its reset and logic functionality.
Example 1: Logic setting 1 or 5: If any of the inputs (IN1, IN2, or L12) are on, then the safety relay
refers to the reset logic.
Example 2: Logic setting 4 or 8: If all three of the inputs (IN1, IN2, and L12) are on, then the
safety relay refers to the reset logic.
EMD Safety Relay
The EMD safety relay has two switches. The combination of the switch settings determines the
functionality and the duration. During configuration, the Time switch determines the duration
of the Range switch. Figure 27 and Table 8 on page 33 show the setting options for the Range
and Time switch.
With the Time switch set to 1 at the start of the configuration process, the duration of the
Range switch is the shorter range.
With the Time switch set to 10 at the start of the configuration process, the duration of the
Range switch is the longer range.
