© PHOENIX CONTACT - 2013-09-16 

## **1 Description** 

Compact timer relay in 6.2 mm housing for controlling time sequences. 

The time is set on the front of the device using a labeled thumbwheel, which is recessed to protect against accidental modification. A screwdriver is used to change the settings (blade width 2.5 mm). 

The compact timer relays are available with different time ranges as well as with a screw, spring-cage, and push-in connection. 

## **Features** 

- 6.2 mm narrow housing 

- With off delay (with control contact) 

- Adjustable time 

- Easy and accurate time setting 

- Supply voltage 24 V DC 

- Output: A floating PDT 

## **WARNING: Correct usage in potentially explosive areas** 

The module is a category 3 item of electrical equipment. Follow the instructions provided here during installation and observe the safety instructions. 

Never carry out work when voltage is present. 

Make sure you always use the latest documentation.

**==> picture [44 x 107] intentionally omitted <==**

**==> picture [44 x 107] intentionally omitted <==**

**NOTE:** Please observe the requirements defined for use in potentially explosive atmospheres! 

**WARNING: Explosion hazard** The device should be installed in a housing (control or distributor box) that fulfills the requirements of EN 60079-15 and at least IP54 (EN 60529) degree of protection. **WARNING: Explosion hazard** When installing and connecting the supply and signal circuits observe the requirements of EN 60079-14. Only devices suitable for operation in Ex zone 2 and the conditions at the application site may be connected to the circuits in zone 2. 

## **WARNING: Explosion hazard** Cables may be connected and disconnected in potentially explosive areas only when power is disconnected. **WARNING: Explosion hazard** 

The device must be stopped and immediately removed from the Ex area if it is damaged or was subject to an impermissible load or stored incorrectly or if it malfunctions.

## **7 Installation** 

## **WARNING: Risk of electric shock** 

Never carry out work when voltage is present. 

The module can be snapped onto all 35 mm DIN rails according to EN 60715. 

UL requirement: Use copper cables approved for at least 75°C. 

## **Power supply** 

The module is supplied with 24 V of DC voltage.

## **8 Time setting** 

**==> picture [238 x 241] intentionally omitted <==**

**----- Start of picture text -----**<br>
A1+<br>A2-<br>B1<br>1 +<br>6<br>– x10%<br>R<br>11<br>14<br>12<br>OFF-CC 0,1-10s<br>**----- End of picture text -----**<br>


The time can be adjusted variably using a screwdriver (blade width 2.5 mm). The value set on the knurled wheel multiplied by 10 gives the percentage set value of the time end value. 

## **Example:** 

Time end range of the time relay = 10 s 

**1** Setting on the knurled wheel = 6 6 x 10 % = 60 % Time end range of the time relay = 10 s 60 % of 10 s = 6 s 

According to the setting of the knurled wheel (1...10), you can also read the time directly from the "Time setting for different time setting ranges" table. 

## **Time settings for various time setting ranges:** 

|**Position**<br>**Knurled wheel**|**0.1 - 10 s**<br>time[seconds]|**3 - 300 s**<br>time[seconds]|**0.3 - 30 min**<br>time[minutes]|**3 - 300 min**<br>time[minutes]|
|---|---|---|---|---|
|0|0,1|3|0,3|3|

The following table shows some examples: All intermediate values (e. g. 1.5) can be adjusted. 

The smallest adjustable time is reached at position "0". No time can be set between "10" and "0". This area is identified with a quickly flashing geed LED.

## **9 Diagnostics** 

The LEDs indicate the following error states: 

## **LED U/t (green, backlighting of the knurled wheel)** 

- Flashes: Voltage is present, the set time is elapsing 

- Flashing quickly: Undefined time range between "10" and "0" adjusted 

- On: Voltage is present, the set time has elapsed 

## **LED R (yellow)** 

- On: The output relay has picked up 

- Off: The output relay is dropped

## **OFF-CC: With off delay with control contact** 

Supply voltage U must be applied permanently to the device (green LED U/t lights up). When control contact A1-B1 closes, the output relay picks up (yellow LED R lights up). If control contact A1-B1 opens, the set time t starts running (green LED U/t flashes). After time t has elapsed (green LED U/t lights up) the output relays drop out (yellow LED R is not lit). If the control contact is closed again before time t elapses, the elapsed time is deleted and restarted with the next cycle.
