T = Set time 1. For time ranges, see page 829.
Ta = Shorter than set time 2. For sockets and accessory part numbers, see page 838.
Ts = 1 Second 3. When power is applied, the NO output contact closes. When power is removed, the timing period
Tr = Minimum Power Application Time begins. When time has elapsed, the NO contact opens.
GT3F-1: 1 Second 4. For the timing diagram overview, see page 794. Terminal Blocks
