Figure 2.6-3 IDMT Characteristics curves
Operate time of DT
(iv)
The operate time in the DT is a constant.
Time characteristic
The user should set DT for the scheme switch [EF1-Timer]. The value of the required operate
time is set for the setting [TEF1] in the range 0.00–300.00s.
Instantaneous activation
The instantaneous operation characteristic is achieved by setting zero for the [TEF1], but the
instantaneous one can be also obtained when the logic signal '1(High)" is programmed to be
injected at the PLC connection point "EF1_INST_OP".
Reset time for IDMT
(v)
Programming the reset time characteristic is available for the IEEE standard, US standard
and original (user-programmable) inverse-time-reset characteristic†. In the IEEE standard,
for example, the user can set DEP for the scheme switch [EF1-Rtimer]. The following equation
