Electric part-turn actuators (hereinafter EA) types UM 2 designed for direct installations onto controlled devices (regulating bodies -valves, etc.). EA of UM 2 types are provided for remote control in both directions of their movement. They can be equipped with means of measuring and control of technological processes where an unified analogue direct current or voltage signal is an information bearer on their input and/or output.
Product protection EA UM 2 does not have own short-circuit protection, therefore there must be included suitable protective device into the supply power (circuit breaker, or fuse), which serves at the same time as main switch. For protection, we recommend to use a fuse type "T"...

UM 2 Observe the valve manufacturer´s instructions with respect to the requirement to ensure switching-off in limit positions through position or torque switches! Caution: 1. Power supply to the actuator and connections with switching, protective and safety devices may be carried out only by personnel with appropriate qualification, in compliance with the corresponding standards and wiring diagrams, such as those specified in the Instruction Manual..
UM 2 4. Adjustment Attention! See chapter 1.2 If it is necessary to connect the supply voltage to Electric actuator, make sure by following the mentioned procedure that there is no injury caused by the electric current. Otherwise, disconnect the Electric actuator from the electricity network.
UM 2 Adjustment of position-signalling unit (S3(S13),S4(S14)) (Fig.6) EA is delivered set to a stroke corresponding to 6 according to table 3 or to a stroke required by customer. The procedure for position switches setting, adjustment a new setting is as follows (Fig. 6, 7): •...

UM 2 4.3 Signaling switches adjustment (S5,S6) (Fig. 8) The signaling switches of EA are at producer preset to switch on about 10% before end positions provided the customer not specified otherwise. Before proceeding with signaling switches adjustment, S3, S4 end position switches must be adjusted according to the previous chapter if necessary.
UM 2 4.5 Adjustment of resistant transmitter (Fig.9) The resistant transmitter is in the EA used to function as a remote position indicator. Before the resistant transmitter adjustment the position switches have adjusted (S3,S4). Adjustment consists in setting of the...

UM 2 4.7 Adjustment of Capacitive Transmitter CPT1/A (Fig.12) The chapter describes adjustment of the capacitive transmitter to the specified parameters (standard values of output signals) in case they are reset. The capacitive transmitter serves as a position transmitter of electric actuators with unified output signal of 4÷20 mA...
UM 2 • Having the transmitter adjusted put the jumper again on the terminals 81 and 82 in case that the output signal wont be used (the circuit through the terminals 81 and 82 should be closed). • Connect the control signal to the terminals 86 and 88 The user has to arrange grounding of the 2-wire circuit of the capacitive transmitter to the electrical ground of a joined controller, computer, etc.
UM 2 If necessary, please change the characteristic of the output signal from descending to ascending or vice versa, according to the following chapter.

UM 2 Leaving calibration mode: • After 10 sec. not working in calibration mode, LED will go out as a signal of leaving calibration mode. If LED is blining, error appears. Transmitter errors: In case of error LED starts blinking. Number of LED blinking means number of error in table No. 4. After longer pause blinking process repeats.
Setting of the controller is performed using buttons and LED diodes. Adjust the position and torque switches and the position transmitter before adjustment of the controller. Laying of adjusters and signaling elements on the board of the REGADA controller is shown on Fig. 14: SW1 button...
UM 2 Controller setting procedure: The initialization routine starts at the switched-on controller, zero system deviation and short pressing of the SW1 button for ca 2 sec (i.e. until the diode D3 got on). Loosing the button some of the default menus starts (usually control signal) what is shown with 1 blink on the D3 diode as well as one of the default parameters (usually control signal of 4-20mA) what is shown with 1 blink on the D4 diode.
UM 2 4.10 Electric local control (Fig.15) -additional equipment In case of need (during adjusting, function checking etc.), but power supply must be provided, is possible to readjust actuator by electric local control. After switching the mode switch to the mode “LOCAL” it is possible by the direction switch to control motion of the output part to setting direction.
