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 [OCN1-Timer]. The value of the required operate
time is set for the setting [TOCN1] in the range 0.00–300.00s.
Instantaneous activation
The instantaneous operation characteristic is achieved by setting zero for the [TOCN1], but the
instantaneous one can be also obtained when the logic signal "1 (High)" is programmed to be
injected at PLC connection point "OCN1_INST_OP".
Reset time of IDMT
(v)
Programming the reset time characteristic is available for the IEEE standard, US standard
and original (user-programmable) dependent time characteristic†. In the IEEE standard, for
example, the user can set DEP for the scheme switch [OCN1-Rtimer]. The following equation
