CCLK-1004

• The CCLK-1004 controller manages 4 digital outputs by schedule, by photocell or by astronomical events. These 4 outputs can be programmed on CCLS-4016 inputs. Each output is activated base on an activation setpoint and a de-activation setpoint assisted by a time setpoint.
• The schedules and the photocell can be use on the same output.
• Actions are performed so as event-driven, that is to say the photocell controls are performed during the transitions with a setpoint regardless of whether a schedule command has arrived before or have been programmed after.
• The CCLK-1004 uses the BACnet communication protocol when integrated with abuilding control system.

Configuration

• The settings of the CCLK-1004 can be done using the main screen or with the Cristal Controls software name «BACnet Browser».
• The main adjustable parameters are setting the lux reading, setpoints or when «on» and «off» will be activated.
• More parameters can also be set for the operation or the network communication.

Operation schedule

• Each of the 4 outputs can have its own weekly schedule.
• Every day of the week can contain up to 4 orders applying to the output.
• These four commands can be at a fixed time or calculated according to the time of sunrise or sunset.
• Can be determined for each output if the calendar dates apply or not. For example, a schedule can control outdoor lighting regardless of the calendar, but another schedule can control indoor lighting taking into account the calendar dates.

Communication

• BACnet network allows reading and writing the 4 outputs status, read the photocell value, read the 0-10V input and set different options.
• CCLK-1004 has a dual speed network port with auto negotiation capability for any 10Mbit or 100Mbit connections.
