Programming / operating the function keys Documentation for routing diagram 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 14 Begin by selecting the function for the device in menu 4.1 1.0 rE1 - Setting of parameters for relay 1 1.1 SEt / SPL - Setting of relay 1 setpoint Possible selections are 0...99.9%. The setpoint is set in % of the input signal. When the selected func tion in menu 4.1 = {004 = Setpoint window}, the low window value SPL is set in this menu.

2.4 dEL - Setting of relay 2 time delay Possible selections are 0...99.9 s. The time delay is the period in which the input value must be present before the relay switches state. 2.5 HyS - Setting of hysteresis for setpoint window Possible selections are 0...99.9%. - Page 16 004 = Setpoint window: Dual trip amplifier with setpoint window on both relays acc. to your choice. The setpoint window is set with a low and an upper value on the input signal thus making the relays active / inactive within the range. In submenus 1.1 / 2.1 the low percentage value of the input signal is set, and in submenus 1.2 / 2.2 the high percentage value of the input signal is set.
