Contact conditioner properties
Each contact can be conditioned with an associated timer that can be selected for pick up,
drop off, dwell, pulse, pick-up/drop-off, straight-through, or latching operation.
"Straight-through" means it is not conditioned in any way whereas "latching" is used to create
a sealed-in or lockout type function.
1. Select the contact name from the Contact Name list (only shown when inserting a new
symbol).
2. Choose the conditioner type required in the Mode tick list.
3. Set the Pick-up Time (in milliseconds), if required.
4. Set the Drop-off Time (in milliseconds), if required.
