Ne vert he less the lo ca ti on should be se lec ted to en su re that no ca pa ci ti ve or in duc ti ve in ter fe rence can have an ef fect on the in stru ment or con nec tion li nes. It is adv isable: • To use shiel ded cables. • The wiring of shields and groung (0V) should be star- sha ped. • The distan ce to inter fe rence sour ces should be as far as pos si ble. If ne cessa ry, pro tec ti ve scre en or me tal en clo su res must be pro vi ded. • Coils of relays must be supplied with filters. • Paral lel wiring of input signals and AC power li nes should be avoi- ded. • The par allel output lines must be as short as pos si ble. • It is necessa ry to use shielded twisted pair cable for the RS422-li nes as well as for the SSI si gnal lines.

The in put fre quen cies come to a dou bling sta ge. At ten ti on must be paid, that the pulse width high to low is about 50% (180° or 1/2 cycle). If both input chan nels are used the se cond in put pulse must have 90° degrees out of phase. When in put frequen cies have pas sed the doubling stages the output frequen cies of the doubling stages are ad ded. By this way input frequen cies can be qua dru pled.
