.. DANGER! Caution! Electric Shock! .. When the power is on, DO NOT touch the AC terminals in case an electric shock may occur. .. Make sure the power is disconnected when you check the unit inside. .. CTA series is an OPEN-TYPE device. They are intended for installation completely within an overall panel and are for use in counting or timing application. If it will cause serious injury to workers or damage on other equipments when used in a dangerous environment, please make sure it is installed in an automatic safety protection device. 1. Precaution 1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width 7.0mm), hole (diameter 3.2mm). Screw size: M3x6.5 (with 6.8x6.8 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire: solid/twisted wire of 2mm2, 12AWG to 24 AWG. Please be sure to tighten them properly. 2. Prevent dust or metallic debris from falling into the device and cause malfunctions. 3. DO NOT modify or uninstall the device. 4. DO NOT use empty terminals. 5. Make sure the wires are correctly connected to proper terminals. 6. Keep away from high-voltage and high-frequency environment during installation in case of interference. 7. Prevent using the device in premises which contain: .Dust or corrosive gas .High humidity .High radiation .Vibration and shock 8. CTA series is an open-type device. Make sure to install it in an enclosure to prevent dust, humidity in case of an electric shock. 9. Please make sure the power cables and signal device are installed correctly before switching on the power; otherwise serious damage may occur.. 10. DO NOT touch the terminals or repair the device when the power is on; otherwise an electric shock may occur. 11. Please wait for one minute after the power is switched off to allow the capacitor to discharge and DO NOT touch the internal wiring within this period. 12. Use dry cloth to clean the device. DO NOT use acid or alkaline liquid to clean the device. 2.

Key Operation Increase and decrease SV or change parameter settings. Left move 1 digit of the selected digit. The indicator of the selected digit will flash. MODE Save the set parameters or switch among functions. LOCK Prevent settings from being changed. Key-protected mode still works after the power is switched off. Press LOCK to enter key-protected mode. In non-key-protected status, press LOCK to enter Lock 1. In Lock 1, press LOCK again to enter Lock 2. Press MODE and at the same time to disable key-protected mode. (Lock 1) disables the functions of all keys. (Lock 2) allows users to change SV and functions of RESET remain. LOCK only functions in non-key-protected status. RESET Clear and reset PV. .. Modes: Operation Mode and Configuration Mode Operation When the power is on, the timer/counter/tachometer is in the operation mode. Press to change SV, or to make change on a desired digit. The indicator of the selected digit will flash. After the change is made, press MODE to save the setting. If SV or parameters are not changed, press MODE once to switch between SET1 and SET2. Configuration Press MODE in operation mode for more than 3 seconds to enter configuration mode. Press MODE once to switch among parameters. To return to operation mode, press MODE for more than 3 seconds. 3. Ordering Information CTA 1 2 3 4 5 6 .. Product name CTA: Delta Counter/Timer/Tachometer A series ..
