Yeah so the capture zone triggers are enabled by default in the prefab. You'll have to disable them for a time with the Disable input.
You could use a logic_timer, and its OnTimer output if you wish.
Setting its Timer setting to 60, and the outputs of:
OnTimer > capture_zone_names > Disable
OnTimer > capture_zone_names > Enable > After a delay of 30
You can also use the Input on the pd logic entity:
SetCountdownTimer > 30
To display a timer on the HUD at the bottom center of a countdown while the capture zone trigger is disabled.
This is also possible to handle entirely within the pd logic entity using the logic entity's OnCountdownTimerExpired output, to affect itself, but that's a little bit less intuitive and user friendly.
For more information on the PD logic entity's settings you can click the in-editor Help key (in the top right) for a full list of KVPs and IO:
