3. Поставување и инсталација
Монтирање:
The GRT8-B2 time relay is designed for DIN rail mounting. Ensure the DIN rail is securely installed in a suitable enclosure, away from excessive heat, moisture, and vibration.
Дијаграм за поврзување:
Refer to the wiring diagrams below for proper connection of the time relay. Always ensure power is disconnected before making any connections.
Слика 3.1: Wiring diagram for GRT8-B2 (2SPDT) showing connections for supply voltage (Un), trigger (S), and output contacts (15-16-18 and 25-26-28). Also includes physical dimensions.
Слика 3.2: Example wiring diagram for GRT8-B2 showing connection to a trigger switch and a load (signal light). Terminals 15-18 (NO) close on power-on and disconnect after delay. Terminals 15-16 (NC) disconnect on power-on and close after delay.
Терминални врски:
- А1(+), А2(-): Набавка волtage input (AC230V).
- S: Trigger terminal for external control (e.g., push button).
- 15, 16, 18: First SPDT output contact. 15 is common, 16 is normally closed (NC), 18 is normally open (NO).
- 25, 26, 28: Second SPDT output contact. 25 is common, 26 is normally closed (NC), 28 is normally open (NO).
4. Упатства за работа
The GRT8-B2 operates in Delay OFF mode (Function B). This means that upon receiving a trigger or power-on, the output contacts will immediately change state, and then revert to their original state after a set delay time.
Поставување време:
Времето на одложување се поставува со помош на две ротирачки копчиња на предната плоча:
Слика 4.1: Time setting knobs. Knob 1 selects the delay gear (s, m, h, d, ON, OFF). Knob 2 provides fine adjustment of the delay time from 10% to 100% within the selected range.
- Копче 1 (Избор на временски опсег): Selects the base time unit (seconds, minutes, hours, days) and the maximum value within that unit. Available ranges include: 0.1-1s, 1-10s, 6-60s, 1-10min, 6-60min, 1-10hr, 0.1-1day, 1-10day. There are also 'only ON' and 'only OFF' settings for continuous operation or immediate disconnection.
- Копче 2 (Процент на времеtage Поставување %): Adjusts the delay time as a percentage (10% to 100%) of the selected time range.
Exampле: To set a 5-minute delay, select the '10m' range with Knob 1 and set Knob 2 to '50%'.
Function Mode B (Delay OFF):
In Delay OFF mode, when power is applied or the trigger (S terminal) is activated, the load connected to the relay's output contacts (e.g., 15-18) will turn ON immediately. After the set delay time has elapsed, the load will turn OFF. If the trigger is held during the delay, the load remains ON until the trigger is released, then the delay starts.
Слика 4.2: Illustration of Delay ON (A) and Delay OFF (B) functions. For Delay OFF (B), after power-up, the light turns on and the relay begins to delay. After the set time (e.g., 10 seconds), the light will turn off.
Operational Demonstration:
Watch the video below for a practical demonstration of how to use a GEYA GRT8-B1 (similar to GRT8-B2) off-delay time relay.
Видео 4.1: A demonstration of the GEYA GRT8-B1 off-delay time relay. The video shows setting the delay, applying power, and observing the load's behavior (light turning on immediately and then off after the delay). It also demonstrates the effect of holding down a reset button during the timing delay.
5. Одржување
The GEYA GRT8-B2 time relay is designed for reliable operation with minimal maintenance. However, regular checks can help ensure its longevity and proper function.
- Визуелна инспекција: Периодично проверувајте го релето за какви било знаци на физичко оштетување, промена на бојата или лабави врски.
- Затегнатост на терминалот: Ensure all screw terminals remain tight to prevent intermittent connections or overheating.
- Чистење: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Еколошки услови: Проверете дали работната средина останува во рамките на наведените опсези на температура и влажност.
6 Смена на проблеми
If the GEYA GRT8-B2 time relay is not functioning as expected, consider the following common issues and solutions:
| Проблем | Можна причина | Решение |
|---|---|---|
| Relay does not activate (LEDs off) | No power supply; Incorrect wiring; Faulty unit. | Проверете го снабдувањето волtage at A1/A2 terminals; Verify wiring according to diagram; Replace unit if faulty. |
