Operate time of DT
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”.
(v)
Reset time for IDMT
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
