Product Details
Brand Name: | Acrel | Place of Origin: | Jiangsu, China | Model Number: | ARD2F |
Product Description
1,Overview
ARD series intelligent motor protector (hereinafter referred to as protector) can perform various conditions such as start timeout, overload, phase failure, unbalance, underload, ground/leakage, blockage, short circuit and external fault during motor operation. Protection, and SOE fault event recording function, convenient for on-site maintenance personnel to find the cause of the fault. Suitable for coal, petrochemical, smelting, electric power, ships, and civil construction. The protector has RS485 remote communication interface, DC 4 ~ 20mA analog output, and PLC, PC and other control machines form a network system. Remote monitoring of motor operation.

Table 7 Additional features
Additional features | Code | Additional features | Code | |
Start control (including K function) | Q | Leakage Protection | L | |
Switch input | K | 4~20mA analog output | M | |
Temperature protection | T | Loss of pressure (anti-shake) | SU(Including voltage and fault recording functions) | |
Alarm (programmable output) | J | SOE event record | SR | |
Communication Interface | Modbus_RTU | C | Voltage function (phase sequence, power, power factor) | U |
2 Modbus_RTU | 2C | |||
tE time protection | tE |
Note: 1. With start control, the protector provides up to 2 start relays for sequentially controlling the closing/opening of the external 2 contactors, thus realizing different starting modes of the motor (such as Y- conversion start, positive and negative Transfer control, auto-coupled step-down start, etc.);
2, the temperature protection measurement range: thermal resistance 100Ω ~ 30kΩ;
3. For customers without display requirements, a 90L display unit must be ordered in a batch of orders for debugging purposes;
4. When the additional function is equipped with leakage protection L, it is necessary to purchase zero-sequence transformers with different apertures according to the actual current.
5. Additional function When selecting SU, you must select Q at the same time. The loss of pressure (anti-shake) is the need to start the control function.
Now.
6. additional features optional 2C and T two.

Cautions
1.For the primary circuit, three-phase current threading direction shall keep consistent, or else, the ground protection will be in error.
2.When the protector is equipped with ground/leakage protection function, the protector wire from the leakage transformer shall be shielded conductor, or else, the measured data may be incorrect.
3.The rated current (P055) of the protector shall be set rationally. If the set value is less than the normal rated working current, the motor may not start normally; if the set value is more than the normal rated working current, the protector cannot provide the normal protection in case of motor fault.
4.If the protector trips, after the fault is eliminated and before the motor is started, please reset the protector, or else, the motor cannot be started.
5.Motor cooling time: 30min.After the motor overload protection actuated (fault displayed as hEAt), after cooling, it can rest due to heat accumulation.
6.In the actual use on the site, as the protector parameter setting is not rational, the motors may be protected together or are not protected. At this moment, all protection functions will be off. All protection parameters of the protector are set again according to all parameters measured during motor normal operation.
7.If all protection parameters of the protector are appropriate, once the motors actuate together, the protector will work. At this moment, the fault cause is searched according to the actuation code of protector.
8.The protector parameters are defaulted during delivery (except the user’s special requirements). The user may enable all protection functions according to the actual need and set all parameters.
9.If the primary current is 1000A, the external transformer is 1000A/5A. When the protector is connected again, the protector with 5A of current is selected and CT transformation ratio is 200.
