“Relay Action”, override relay states by programmed states
Models providing relay outputs allow to temporary change the actual relay states according to a
programmable ON / OFF pattern, or to temporary freeze the actual switching states. These
override functions can be activated by either touching a front key or by a remote command.
9.3.1.
Override relay/output states by programmable ON / OFF states
Parameter “Relay Action” allows to select which of the relays/outputs should be affected by the
override action. Parameter “Action Polarity” provides setting of the desired “ON / OFF” pattern»
(see section
7.2.9
, “Switching Menu”). The desired way of activation this override command can
be set by the “Command-Menu” (see
7.2.6
).
Application example:
You would like to temporary de-energize relays K1 and K3 by touching the key “UP”, whilst relay
K2 should continue to function normally.
Action
Parameter settings
1
Assign the Override Command to key “UP”
Key Up Func. = 2
2
Select relays/outputs K1 and K3
Relay Action = 5
3
Set the desired switching state of the
relays/outputs (both de-energized)
Action Polarity = 2
9.3.2.
Freeze the actual switching state of all relays
This function will temporary freeze all relays in their actual state for the duration where you press
a key or apply a remote command. During the freeze period the relays will no more follow any
changes of the input frequency
Application example:
You would like to freeze all relays by applying a “High” signal to input “Control1”
Action
Parameter settings
1
Assign the Freeze command to input “Control1”
Input 1 Func. = 2
2
Set the input to “Active High” characteristics
Input 1 Config = 1
3
Assign the “Freeze relays” function to the input
Relay Action = 8
These commands will override the switching states of the selected relays/outputs. All
relays/outputs will immediately return to the actual control state after removing the
override command. All internal measuring and control cycles will continue normally.
To use these functions, please set the corresponding key and input characteristics to
static operation only, since dynamic (edge-triggered) operation would make no sense
