The switches, which do not turn infinitely, should not be turned beyond their limits. 2. Since changing the setting during timer operation my cause malfunction, turn power off before changing. ## **Safety Precautions** Special expertise is required to use Electronic Timers. - All Electronic Timer modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or fail safe provision to the control system when using the Electronic Timer in applications where heavy damage or personal injury may occur should the Electronic Timer fail. - Install the Electronic Timer according to instructions described in this catalog. - Make sure that the operating conditions are as described in the specifications. If you are uncertain about the specifications, contact IDEC in advance. - In these directions, safety precautions are categorized in order of importance to Warning and Caution. ## **Warning** Warning notices are used to emphasize that improper operation may cause sever personal injury or death. ## **Caution** Caution notices are used where inattention might cause personal injury or damage to equipment. - The Electronic Timer is designed for installation in equipment. Do not install the Electronic Timer outside equipment. - Install the Electronic Timer in environments described in the specifications. If the Electronic Timer is used in places where it will be subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, or excessive shocks, then electrical shocks, fire hazard, or malfunction could result. - Use an IEC60127-approved fuse and circuit breaker on the power and output line outside the Electronic Timer. - Do not disassemble, repair, or modify the Electronic Timer. - When disposing of the Electronic Timer, do so as industrial waste. - Turn power off to the Electronic timer before starting installation, removal, Wiring, maintenance, and inspection on the Electronic Timer. - Failure to turn power off may cause electrical shocks or fire hazard. - Emergency stop and interlocking circuits must be configured outside the Electronic timer. If such a circuit is configured inside the Electronic Timer, failure of the Electronic timer may cause malfunction of the control system, or an accident. **800-262-IDEC** (4332) • USA & Canada 859 **GT3 Series Accessories** **Timers** ## **GT3 Series** ## **Accessories** ## **DIN Rail Mounting Accessories** ## **DIN Rail/Surface Mount Sockets and Hold-Down Springs** |DIN Rail Mount Socket|DIN Rail Mount Socket|DIN Rail Mount Socket|DIN Rail Mount Socket|Applicable Hold-Down Springs|Applicable Hold-Down Springs| |---|---|---|---|---|---| |Style|Appearance|Use with Timers|Part No.|Appearance|Part No.| |8-Pin Screw Terminal<br>(dual tier)<br>GT3A-1, 2, 3 (8-pin)<br>GT3F-1, 2 (8-pin)<br>GT3W (8-pin)<br>SR2P-05||||SFA-203<br>,|| |11-Pin Screw Terminal<br>(dual tier)<br>GT3A-1, 2, 3 (11-pin)<br>GT3A-4, 5, 6<br>GT3F-1, 2 (11-pin)<br>GT3W (11-pin)<br>SR3P-05|||||| |8-Pin Fingersafe Socket<br>GT3A-1, 2, 3 (8-pin)<br>GT3F-1, 2 (8-pin)<br>GT3W (8-pin)<br>SR2P-05C|||||| |11-Pin Fingersafe Socket<br>GT3A-1, 2, 3 (11-pin)<br>GT3A-4, 5, 6<br>GT3F-1, 2 (11-pin)<br>GT3W (11-pin)<br>SR3P-05C<br>i":|||||| |8-Pin Screw Terminal<br>GT3A-1, 2, 3 (8-pin)<br>GT3F-1, 2 (8-pin)<br>GT3W (8-pin)<br>SR2P-06<br>~~a~~<br>~~:~~<br>~~|~~||||SFA-202<br>aS<br>~~ee~~|| |11-Pin Screw Terminal<br>GT3A-1, 2, 3 (11-pin)<br>GT3A-4, 5, 6<br>GT3F-1, 2 (11-pin)<br>GT3W (11-pin)<br>SR3P-06<br>~~a~~<br>~~:~~<br>~~|~~|||||| ## **Installation of Hold-Down Springs** **==> picture [483 x 111] intentionally omitted <==** **----- Start of picture text -----**<br> DIN Rail Mount Socket Panel Mount Socket<br>Insert the springs into the outer<br>slots with the projections Insert the springs Hold-down Spring<br>facing inside. into the slots.

The inrush current and steady-state current must be taken into consideration when specifying a timer. ## **Contact Protection** Switching an inductive load generates a counter-electromotive force (back EMF) in the coil. The back EMF will cause arcing, which may shorten the contact life and cause imperfect contact. Application of a protection circuit is recommended to safeguard the contacts. ## **Temperature and Humidity** Use the timer within the operating temperature and operating humidity ranges and prevent freezing or condensation. After the timer has been stored below its operating temperature, leave the timer at room temperature for a sufficient period of time to allow it to return to operating temperatures before use. ## **Environment** Avoid contact between the timer and sulfurous or ammonia gases, organic solvents (alcohol, benzine, thinner, etc.), strong alkaline substances, or strong acids. Do not use the timer in an environment where such substances are prevalent. Do not allow water to run or splash on the timer. ## **Vibration and Shock** Excessive vibration or shocks can cause the output contacts to bounce, the timer should be used only within the operating extremes for vibration and shock resistance. In applications with significant vibration or shock, use of hold down springs or clips is recommended to secure a timer to its socket. ## **Time Setting** The time range is calibrated at its maximum time scale; so it is desirable to use the timer at a setting as close to its maximum time scale as possible. For a more accurate time delay, adjust the control knob by measuring the operating time with a watch before application. ## **Input Contacts** Use mechanical contact switch or relay to supply power to the timer. When driving the timer with a solid-state output device (such as a two-wire proximity switch, photoelectric switch, or solid-state relay), malfunction may be caused by leakage current from the solid-state device. Since AC types comprise a capacitive load, the SSR dielectric strength should be two or more times the power voltage when switching the timer power using an SSR. Generally, it is desirable to use mechanical contacts whenever possible to apply power to a timer or its signal inputs. When using solid state devices, be cautious of inrushes and back-EMF that may exceed the ratings on such devices. Some timers are specially designed so that signal inputs switch at a lower voltage than is used to power the timer (models designated as “B” type). ## **Timing Accuracy Formulas** Timing accuracies are calculated from the following formulas: = ± 1 x Maximum Measured Value – Minimum Measured Value x 100% **Repeat Error** 2 Maximum Scale Value = ± Tv - Tr x 100% **Voltage Error** Tr Tv: Average of measured values at voltage V Tr: Average of measured values at the rated voltage = ± Tt - T20 x 100% **Temperature Error** T20 Tt: Average of measured values at °C T20: Average of measured values at 20°C = ± Average of Measured Values - Set Value x 100% **Setting Error** Maximum Scale Value Hipec **www.IDEC.com** 880
