CAUTION or WARNING: Tells you about the risk of electrical shock. CAUTION, WARNING or IMPORTANT: Tells you of circumstances or practices that can effect the instrument’s functionality and must refer to accompanying documents. TIP: Provides you helpful hints. 1 PART 1 INTRODUCTION 1.1 Description This device can be purchased as monitor (read process value only) or as a controller. • The iSeries controller offers unparalleled flexibility in process measurement. Each unit allows the user to select the input type, from 10 thermocouple types (J, K, T, E, R, S, B, C, N and J DIN), Pt RTDs (100, 500 or 1000 ., with either 385 or 392 curve), DC voltage, or DC current. The voltage/current inputs are fully scalable to virtually all engineering units, with selectable decimal point, perfect for use with pressure, flow or other process input. • The temperature control can be achieved by using on/off or PID heat/cool control strategy. Control can be optimized with an auto tune feature. The instrument offers a ramp to setpoint with timed soak period before switching off the output. • The iSeries device features a large, three color programmable display with capability to change a color every time the Alarm is triggered. The standard features include dual outputs with relay, SSR, dc pulse, analog voltage or current. Options include programmable RS-232 or RS-485 serial communication and excitation. Analog Output is fully scalable and may be configured as a proportional controller or retransmission to follow your display. Universal power supply accepts 90 to 240 Vac. Low voltage power option accepts 24 Vac or 12 to 36 Vdc. 2 1.2 Safety Considerations This device is marked with the international caution symbol. It is important to read this manual before installing or commissioning this device as it contains important information relating to Safety and EMC (Electromagnetic Compatibility). This instrument is a panel mount device protected in accordance with EN 61010-1:2001, electrical safety requirements for electrical equipment for measurement, control and laboratory. Installation of this instrument should be done by qualified personnel. In order to ensure safe operation, the following instructions should be followed. This instrument has no power-on switch. An external switch or circuit- breaker shall be included in the building installation as a disconnecting devi...
