This document describes the GEYA GRT8 Series Digital Display Time Relay, a versatile device designed for various industrial and control applications.

Function Description

The GEYA GRT8 Series Digital Display Time Relay is a multifunctional device capable of controlling industrial equipment, lighting, heating elements, motors, and fans. It offers 20 distinct delay modes, covering a broad delay range from 0.1 seconds to 99 days. These modes include:

• 5 delay modes controlled by power supply: These modes activate based on the presence or absence of power to the relay. Examples include "On Delay (Power On)" where the output contact closes after a set delay t once power is applied, and "Interval (Power On)" where the output contact closes immediately upon power-on and disconnects after delay t.
• 13 delay modes controlled by signal: These modes respond to an external control signal (S terminal). Examples include "Latching relay" where the output contact state changes with each connection of the S terminal, and "Repeat cycle with external control (Starting Off)" where the relay cycles between closed and open states based on delays t1 and t2 as long as the S terminal is connected. Other signal-controlled modes include "On delay with external control," "Off delay with external start," "Pulse I with external start," "Pulse II with external start," "On/off delay with external control," "Pulse generator with external start," "Start-stop," "Double delay off with external control," "On delay I by external start," and "On delay II with external start."
• ON, OFF mode: These modes provide continuous ON or OFF states, such as "Always ON" where the relay is continuously closed when energized, and "Always OFF" where the relay is continuously disconnected regardless of power.

The relay's status is indicated by an LED. The device is designed for 1-MODULE, DIN rail mounting.

Important Technical Specifications

The GRT8 Series time relay is available in two contact configurations: GRT8-X1 (1×SPDT) and GRT8-X2 (2×SPDT).

• GRT8-X2: W240-82g, A230-81g Standards: EN 61812-1, IEC60947-5-1

Usage Features

The GRT8 Series time relay features a digital display for easy monitoring and setting. Setting Delay Time:

• Fast Adjustment: A short press of the "Set" button enters the fast setting interface. Subsequent short presses adjust the parameter value, while a long press enables rapid adjustment. Values exceeding 99 will reset to 0.
• Delay Function Setting: A long press of the "MD" button (3 seconds) enters the function mode parameter setting interface. Here, users can select from the 20 available functions (01-20). Within this interface, short presses adjust parameter values, and long presses enable rapid adjustment. If no key operation occurs within 60 seconds, the device automatically exits the setting mode. Users can also press and hold the "MD" button for 3 seconds to exit and save settings.
• Time Base Setting: The device allows setting the time base for delays (e.g., seconds, minutes, hours, days, or fractions thereof). This option may not be available for single delay time modes.
• Timing Display Mode: Users can select between "Positive timing" and "Count down" display modes.

Wiring Diagram: The manual provides clear wiring diagrams for both 1×SPDT and 2×SPDT configurations, illustrating connections for A1, A2 (supply), S (control signal), and the output contacts (15, 16, 18 for SPDT; 15, 16, 18, 25, 26, 28 for 2×SPDT).

Example Use Cases: The manual illustrates practical applications:

• Case 1 (Mode 07, PNP Sensor): When a PNP sensor detects a signal, the relay acts (15-18 closed), activating a ventilation fan. When the signal is lost, the relay disconnects after a delay t, stopping the fan.
• Case 2 (Mode 03): The ventilation fan cycles on for 10 hours and off for 1 hour.
• Case 3 (Mode 02): Upon power-on, the relay closes (15-18), activating a water pump. After delay t, the relay disconnects, stopping the pump.
• Case 4 (Mode 08, Trigger Button): Pressing a trigger button activates the relay (15-18 closed), turning on an LED. After delay t, the relay disconnects, and the LED turns off.

Maintenance Features

Caution: All products must be installed by qualified electricians, and all electrical connections must comply with appropriate safety standards. Disposal of Electrical Waste: All electrical waste should be disposed of in compliance with current WEEE regulations.
