Time control unit

For interlock control system

Characteristics

Some interlock systems require that some doors open only after a certain time delay, e.g. if the quality/temperature of the air in the interlock must reach a certain level before the door to the clean room may open. The DICTATOR time control unit permits the locking of max. 6 clean room doors against up to 6 “blackroom” doors. If one or several of the “blackroom” doors are opened during the locking time, the time control unit starts the count-down again. Only when the adjusted time has elapsed, the door to the clean room can be opened.

Function

The type of door (clean room or blackroom) is determined by the connection of the control terminals to different terminal strips of the time control unit. The required period (16 different values possible) is adjusted in the time control unit with the help of 4 DIP switches. If a time different from the 16 adjusted periods is required, this has to be indicated in the order as it has to be programmed in production.

The time control unit has a 7-segment display and an additional dot. If the time control unit is on, the dot of the display lights up. When the time control unit is activated by one of the connected terminals, the dot starts flashing (one flash per second). When all blackroom doors are closed, the countdown starts. The time control unit divides the adjusted period in 10 intervals and the display counts down from 9 to 0, thus indicating the remaining time during which the doors will stay locked.

Models / Components

It is possible to connect up to 6 additional displays (part no. 710805) to the time control unit. Independantly of the amount of additional displays, one extension module (part no. 710808) is always required.

The time control unit is connected with a normal cable directly to the distribution box. The extension module for the additional displays is simply plugged on the circuit board of the time control unit (ATTENTION: this changes the construction depth to a minimum depth of 70 mm!). The additional displays are connected in series to the extension module using the adapter set 710925SET. The length of the connecting cables can thus be determined by the customer as required. For the connection of the adapters, on-site cables and 10-pole luster terminals must be used. One adapter set, part no. 710925SET, is required per module/display.
