Frequently Asked Questions - ERTC-01-DIN ENTES

How do I select the operating function on the ERTC-01-DIN?

Press the SET button for 3 seconds to enter programming mode. Use UP and DOWN buttons to cycle through functions (dLYOn, dLYOFF, dO Cnt, FLSHER). Press SET to confirm. The selected function LED will blink.

What is the time range and accuracy of the relay?

The time range is from 1.0 second to 100 hours. Accuracy is ±0.5% or ±20 ms (whichever is greater), with repetition error of ±0.1%.

How do I start, stop, or reset counting?

Connect the Start, Stop, or Reset inputs to GND to activate. You can also use front panel shortcuts: press SET+UP for Start, SET+DOWN for Stop, and DOWN+UP for Reset.

Can I use the relay with both 120V and 230V AC?

Yes, the operating voltage is 230 V AC or 120 V AC with a range of 190-260 V AC or 90-140 V AC respectively. The device automatically adapts to the connected voltage.

How do I set the time value for a function?

After selecting the function, press SET to see the old time value blinking. Use UP and DOWN to adjust digits (leftmost digit changes first). Press SET to confirm and store in non-volatile memory.

What does the Flasher mode offer and how do I configure it?

Flasher mode continuously toggles the relay with adjustable tON and tOFF times. You can choose start mode StOFF (starts with off period) or StOn (starts with on period). The sequence repeats indefinitely.

What safety precautions should I follow during installation?

Always disconnect all power before working. Do not remove the front panel while connected. Clean only with a dry cloth; no solvents. Use only for rack/rail mounting and ensure correct terminal wiring.

Does the device have memory retention during power loss?

Yes, the programmed function and time values are stored in non-volatile memory, so settings are retained even when power is removed.

What is the maximum load the output relay can handle?

The output relay is a 1 change-over contact rated for 8A at 250V AC (2000VA). Ensure the connected load does not exceed these ratings.

How do I clean and maintain the ERTC-01-DIN?

Switch off and disconnect power. Clean the front panel with a soft, dry cloth. Do not use liquids, solvents, or abrasive cleaners. No internal maintenance is required by the user.

USER MANUAL ERTC-01-DIN ENTES

ERT/ERTC-01 is a microcontroller controlled programmable time relay device with a wide range of time scale designed to operate in one of 4 different functions that are On delay, Off delay, Down timer, Flasher modes. Output relay is controlled by set value that can be set between 1.0 sec – 100 hours. Programmed function and set values are recorded at non-volatile memory. Functions and set values can be programmed easily by buttons on the front panel. ERT/ERTC-01 has optically isolated Start, Stop and Reset inputs.

Functions:

On Delay: In the On Delay mode, after the device is energized, the timer starts to count up and when it reaches the adjusted time, the relay is energized. (dLYOn)

Off Delay: In the Off Delay mode, after the device is energized and with start input, the relay is energized and becomes de-energized at the end of the time adjusted by the user. (dLYOFF)

Down Timer: In the Down Timer mode, after the device is energized, the down counter starts to count down from the time adjusted by the user and when it reaches zero, the relay is energized. (dO Cnt)

Flasher: In the Flasher mode, after the device is energized, when tOFF time ends the relay is energized and becomes de-energized at the end of the tOn delay (FLSHEr). The starting mode of the flasher mode can be chosen with StOFF or StOn. In the StOFF mode flasher starts with tOFF and energized after the tOFF value, then continues to tOn mode. In the StOn mode flasher starts with tOn and deenergized after the tOn value, then continues to tOFF mode. The Flasher function is continuously repetitive. Inputs: Start input is used to begin counting, Stop input is used to end counting and Reset input is used to clear counter in dIYOn,dlyOFF and FLSHEr. In dO Cnt mode reset, sets the dO Cnt value. One of this three inputs activated by connecting them to GND.

Function Select:

The device is programmed by pressing the SET button for 3 secs. Then program menu starts with blinking of dLYOn. With UP and DOWN button desired mode dLYOn, dLYOFF, dO Cnt or FLSHER, and the mod led blinks. After pressing the SET button display stops blinking that this mode is chosen. Pressing once to SET button shows the old time value of this mode with blinking and this could be adjusted with UP and DOWN button. Pressing to UP or DOWN button continuous, increases or decreases the left digit. For all the other functions, the left digit is changed the same way. After adjusting the time value, pressing the SET button stops the display blinking, but led button still blinks (Note that this setting operations need a few steps more for FLSHER mode). After pressing the SET button last time mod led stops blinking, desired mod and value are set and writed to non-volatile memory.

Device can be started to counting with start input. With stop input device stops counting until stop input is deactivated. Reset input resets the time values. Device can be started with pressing set and up button at same time (same function with start input). Pressing set and down button at the same time stops counting. (same function with stop input). Pressing DOWN and UP button at the same time resets counting (same function with RESET input).

Precautions For Installation and Safe Use

Failure to follow those instructions will result in death or serious injury. - Disconnect all power before working on equipment.
- When the device is connected to the network, do not remove the front panel.
- Do not try to clean the device with solvent or the like. Only clean the device with a dried cloth.
- Verify correct terminal connections when wiring.
• Electrical equipment should be serviced only by your compedent seller.
- Only for rack panel mounting.

No responsibility is assured by the manufacturer or any of its subsidiaries for any consequences arising out of the use of this material.
