5-41 On Delay, Relay
Array [2], (Relay 1 [0], Relay 2 [1])
Range: Function:
0.01 s* [0.01 - 600 s] Enter the delay of the relay cut-in time.
Select 1 of 2 internal mechanical relays in
an array function. See 5-40 Function Relay
for details.

Enter the delay of the relay cut out time.
Select 1 of 2 internal mechanical relays in
an array function. See 5-40 Function Relay
for details. If the selected event condition
changes before a delay timer expires, the
relay output is unaected.

5-5* Pulse Input
The pulse input parameters are used to dene an
appropriate window for the impulse reference area by
conguring the scaling and lter settings for the pulse
inputs. Input terminal 29 or 33 acts as frequency reference
inputs. Set terminal 29 (parameter 5-13 Terminal 29 Digital
Input) or terminal 33 (5-15 Terminal 33 Digital Input) to [32]
Pulse input. If terminal 29 is used as an input, set
parameter 5-02 Terminal 29 Mode to [0] Input.
