General

This overload devices are designed to prevent the loads getting harm from over currents and ability of control at the same time.TRM-03, TRM-12 and TRM-25 are have internal current tansformers.

Usage of Device and Working Principle

Make the connection of the device according to the connection diagram. Energize the device after making the connections. The display shows the set values for 5 seconds when the devices is energized.When the device is energized, you can make a overload adjustment with the "A>" knob While the setting is being made, the set value is shown on the left display. You can set the delay time with the "t" knob. Wtrine the setting is being made, the set value is shown on the left display. When th device is energized, the relay is energised, the contact output goes to terminal 3 and "OUT" led is on If the currents is higher than the set high current (A>), the device is counts the delay time and ERR on. After the time has elapsed, the relay is de-energised, the contact output goes to terminal 1, and "OUT" led is goes out. Delay time (Start Current): After the relay is energized or reset, the device does not current control for 5 seconds. Allows to delay time. Asymmetry: If there is more than 50% difference between the highest and lowest current passing on the phases, the device will enter asymmetry fault within 2 seconds. (When the motor starts, if a phase loss occurs, the motor can be prevented from being damaged.) When the device enters the asymmetry error, the display group of the two phases causing the fault flashes and error LED is on. If the current is less than these values, the device does not control asymmetry. 0,1A for TRM-03, 1A for TRM-12 and 2A for TRM-25. The device must be manually "Reset" button or power off to exit asymmetric errors.

Reset Modes

Note: Press the SELECT button for 10 seconds to change the mode. The mode light will change.

Warnings

Warnings - Please use the device according to the manual. - Don't use the device in wet. - Include a switch and circuit breaker in the assembly. - Put the switch and circuit breaker nearby the device, operateycan reach easily. - Mark the switch and circuit breaker as releasing connection for device. - Maximum currents to be applied to the devices; 3A for TRM-03, 12A for TRM-12 and 25A for TRN If current is applied above these values, the device may make incorrect measurement or damage echnical .

Maintenance

Switch off the device and release from connections. Clean the connection point of device with a swab. Don't use any conductor or chemical might damage the device. Make sure device works after cleaning
