EPCR02 - Current Protection Relay
Technical Specifications
OPERATING
ENDA Current protection relays are designed for in order to protecting the atached systems from overcurrent or low-current loads.
Before device is turned on, timing, set and mode values must be set.
1- Overcurrent Protection :
For this mode potentiometer must be on UpL position.
When device is powered, output relay status will be ON. During the first operation, system will loaded
overcurrent at momentary. For this reason, in order to avoid the device from entering the error mode,
start delay time activated. At the end of this period, if the measured current greater than adjusted set
value, error condition activated. During this time, current value does not below the set value, output
relay status will be OFF. Device restarts after 5 sec delay time but the start button must be pressed for
running the system.
2- Low-current Protection :
For this mode potentiometer must be on LoL position.
When device is powered, output relay status will be ON. During the first operation, in order to avoid the
device from entering the error mode, start delay time activated. At the end of this period, if the measured
current lower than adjusted set value, error condition activated. During this time, current value does not
upper the set value, output relay status will be OFF. Device restarts after 5 sec delay time but the start
button must be pressed for running the system
CONTROL
Start delay time (t ) 1, 2, 6, 8, 10 sec, can be selected on device.
s
Error delay time (t ) e 0.5, 1, 2, 3, 4, 5 sec, can be selected on device.
Current set value (A) 0.5, 1, 2, 3, 4, 5 A AC can be selected on device.
Overcurrent protection Mode potentiometer must be on UpL position.
Low-current protection Mode potentiometer must be on LoL position.
Current frequency range 45-65 Hz.
