Function description
Starting automatics are used to switch on, for example, electric motors or other inductive loads with a time delay. This is an important feature to ensure trouble-free starting.
When switching on electric motors, high inrush currents occur, which can be approximately six times the rated current. If two motors are switched on simultaneously, the starting currents can reach a level where the upstream fuse may trip. To prevent this, the second drive is switched on with the help of a delayed start. This also has the added advantage that the second drive automatically switches on after approximately 1-4 seconds without any further operation and automatically switches off with a time delay after the main drive is turned off.
This is a useful feature for extraction devices and much more.
Description CCST
CCST with fixed time and variable on/off time and switching threshold, 3 potentiometers
The delayed control receives its operating voltage through the terminals L1 and N.
The control signal for the delayed control is the load current of the connected consumer. The controlling consumer is connected between the terminals L1 Load and N.
When the consumer is switched on, the relay engages with a delay and the contact SP is connected to the terminal N. When the load current stops, the relay opens again with a delay. The contact SP controls a contactor, for example, for an extraction system.
Depending on the model, the unit may only be operated at 230V or 400V.
There must be a protection mechanism for this unit before this module.
If a potential-free switch contact is required, the bridge (plated hole) between the terminals N and NSP must be separated with a 3mm drill. The copper ring around the hole should be completely removed. The switch contact of the relay then lies between SP and NSP.
