Protection and monitoring elements already have their own programmable delay timers, where they are
required. For additional flexibility, 10 independent timers are available for implementing custom schemes
where timers are not available. For example, a pickup delay timer may be required on a logic input; or, a single
delay timer may be required on the output of a block of logic.
This section contains the settings to configure timers 1 to 10.
