1.0 General This specification guide covers the general requirements for design, information/ manufacturing and installation of electronic timers. Introduction

2.0 Product features/ The devices shall be designed for all time-delayed switching product functions operations in control, starting, protective and regulating circuits. They shall be available with many timing functions or modes of operation.

The timers shall be able to provide the following time delay functions (single function and multifunction devices):

- ON-delay/ Delay on make - OFF-delay, with auxiliary voltage/ Delay on break - OFF-delay, without auxiliary voltage/ True OFF-delay - Impulse-ON/ Interval - Pulse former/ Single shot - Impulse-OFF, with auxiliary voltage / Trailing edge interval - Impulse-OFF, without auxiliary voltage/ True trailing edge interval - Flasher, starting with “ON”/ Recycling equal times-ON first - Flasher, starting with “OFF”/ Recycling equal times-OFF first - Star-delta change-over - Switching relay/ Interface relay

The desired function shall be able to be pre-selected with a front- sided rotary switch with multifunction devices and the desired time delay shall be able to be set by a potentiometer with direct reading scale. Each multifunction device shall be able to operate on 8 time ranges (0.05s-100h). Each single-function device shall be able to operate on a single time range (0.1-10 s, 0.3-30 s, 3-300 s or 0.3-30 min.)

The output contact of the device should be type 1c/o or solid-state output for high switching frequencies.

The product shall be provided with the following LED indications:

- Output relay energized (preferably red LED) - Supply voltage (preferably green LED)

The timers shall be ABB type CT-E range or pre-approved equal.

220-240 V AC 380-415 V AC 24-240 V AC 24 V AC/DC Frequency, AC supply 50/60 Hz or DC (0 Hz) Number of output contacts 1 c/o Rated switching voltage (IEC 60947-1) 250 V AC / 250 V DC Rated switching current (IEC 60947-5-1): AC12 (resistive) @ 230 V 4 A AC15 (inductive) @ 230 V 3 A DC12 (resistive) @ 24 V 4 A DC13 (inductive) @ 24 V 2 A Operating temperature range -20 °C … +60 °C Storage temperature range -40 °C … +85 °C

6.0 Mechanical The timer should be realized in a 22.5 mm wide enclosure, possible requirements to be mounted on DIN rail according to EN 50022. The connection terminals should be able to accept stranded wires in the size of 2 x 1.5 mm2 (2 x 16 AWG) with wire end ferrule. The mounting position of the device in a cabinet should not be limited. According to IEC 68-2-6 the product should have a mechanical resistance of 10 g and an operational reliability of 6 g.

7.0 Quality The vendor shall be certified in accordance to ISO 9001 (quality requirements management system) and ISO 14001 (environmental certification). A complete environmental product declaration (EPD) shall be available upon request. The EPD shall describe the material used for the timer, energy consumption, losses, etc. The product shall be functionally tested prior to shipment to assure proper operation per specification.

8.0 Documentation The device shall be shipped with an operation and instruction sheet including functional diagrams, connection diagrams and set up information.

9.0 Startup and Startup procedures shall be intuitive and simple enough so as not to adjustment require factory assistance or training. All adjustments shall be made from the front of the timer by using rotating switches with direct reading scales.

10.0 Accessories As accessory a remote potentiometer, an adapter for panel mounting, and a sealable cover should be available.
