Timing System
The timing system on the DVS3 mk2 is flexible and transparent in operation. Step changes of any quality may be generated by typing in value using the keypad. Entering a value in this way automatically resets and starts the timer when the change is applied. The timer then stops on a change of state of either contact input. More complex timing functions are handled by the PF-F-PF mode.
Two contact inputs are provided, both of which have LED's and a mimic on the display to show the contact state. The contact inputs auto-select for normally open or normally closed contacts, A DC voltage can also be used to trigger the timer using the Vdc contact.

Protection and Safety
The DVS3 mk2 is CE marked and is designed to meet the requirements of BS EN61010. The outputs are protected by overcurrent and thermal trips, and the contact inputs are protected by PTC thermistor. The phase lock current input is fuse protected, and the voltage input is impedance protected. An earth terminal is provided for connection to a local earth.
