5-41 On Delay, Relay
Array [8](Relay 1 [0], Relay 2 [1], Relay 3 [2], Relay 4 [3], Relay 5 [4], Relay 6 [5], Relay 7 [6], Relay 8 [7], Relay 9 [8])
Range: Function:
0.01 s* [0.01 - 600.00 s] Enter the delay of the relay cut-in time. Select one of available mechanical relays and MCB 105 in
an array function. See par. 5-40
Function Relay
. Relay 3-6 are included in MCB 113.
5-42 Off Delay, Relay
Array [8] (Relay 1 [0], Relay 2 [1], Relay 3 [2], Relay 4 [3], Relay 5 [4], Relay 6 [5], Relay 7 [6], Relay 8 [7], Relay 9 [8])
Range: Function:
0.01 s* [0.01 - 600.00 s] Enter the delay of the relay cut-out time. Select one of available mechanical relays and MCB 105 in
an array function. See par. 5-40
Function Relay
.
If the selected Event condition changes before the on- or off delay timer expires, the relay output is unaffected.
3.7.6 5-5* Pulse Input
The pulse input parameters are used to define an appropriate window for the impulse reference area by configuring the scaling and filter settings for the
pulse inputs. Input terminals 29 or 33 act as frequency reference inputs. Set terminal 29 (par. 5-13
Terminal 29 Digital Input
) or terminal 33
(par. 5-15
Terminal 33 Digital Input
) to
Pulse input
[32]. If terminal 29 is used as an input, then set par. 5-02
Terminal 29 Mode
to
Input
[0].
