TRIP AMPLIFIER 2231 • AC/DC trip amplifier • 2 adjustable alarm limits • Galvanically isolated 3.75 kVAC • Front programmable • 3-digit LED display • 24 VDC or universal supply Applications Alarm detector in connection with measurement of AC/DC current or voltage signals. -
Page 9: Functions
Functions The front-operated push buttons are used for programming of the different standard functions. Single or dual trip amplifier can be selected. Dual trip amplifier with relay 2 as pre-setpoint, single or dual trip amplifier with hysteresis in each relay, which is set as setlow or sethigh and dual trip amplifier with hold on relay 2 until relay 1 is activated. -

Page 16: Routing Diagram
PROGRAMMING / OPERATION THE FUNCTION KEYS DOCUMENTATION FOR ROUTING DIAGRAM General The programming is menu-controlled. The main menus are numbered in level 0 (x.0), and the submenus are numbered in level 1 (x.1 to x.5). Each submenu has an accompanying entry menu. The menus are structured in such a way that the menus most frequently used are closer to the default menu 0.0. - Page 17 When menu 4.2 has been selected, EFS - Enable Fast SETTING, fast setpoint change is possible by activating the Fast Setting function. In this menu, the function keys have a special feature as 1 increases the setpoint and 3 decreases the setpoint from the value it had when activated. Activating for more than 2 s automatically activates the increment / decrement function.
- Page 18 1.3 InC / dEC - Setting of active relay 1 for increasing / decreasing input signal Possible selections are InC or dEC. If InC is selected, relay 1 will be activated when the input value is high er than the setpoint and deactivated again, when the input value is lower than the setpoint minus the hysteresis.
- Page 19 2.2 HYS / SPH - Setting of relay 2 hysteresis Possible selections are 0...99.9%. The hysteresis is set in % of the input signal. The hysteresis is the difference between the setpoint and reset values.When the selected function in menu 4.1 = {004 = Setpoint window}, the upper window value SPH is set in this menu.

3.0 Aln - SETTING OF SIGNAL INPUT 3.1 U / I - Display of input type There are two alternative displays when setting JP1 on the PCB, U and I. The input type is detected by JP1. When JP1 is installed in “I”, “I” will be displayed, and the input signal range is set in current. - Page 21 001 = Single setpoint: Single trip amplifier set in main menu 1.0 with setpoint within the range 0...99.9% of the input signal. The hysteresis is set in the range 0...99.9% of the input signal. The parameter selection determines whether the trip amplifier should be active for increasing (InC) or decreasing (dEC) input signal.
- Page 22 In submenus 1.3 / 2.3 InC increasing / dEC decreasing, the relay func tion is determined within the setpoint window. If InC is selected, the relays are active; if dEC is selected, the relays are inactive. The time delay is set in the range 0...99.9 s.
