Wiring
Keep mains cables separate from signal and measuring cables. We recommend twisted
and screened measuring cables (screen connected to earth).
Connected final elements must be equipped with protective circuits to manufacturer
specification. This avoids voltage peaks which can cause trouble to the
controller.
The instruments must be protected by an individual or common fuse for a max. power
consumption of 10 VA per unit (standard fuse ratings, min. 1.0 A).
Signal and measurement circuits may carry max. 50 V r.m.s. against ground, mains
circuits may carry max. 250 V r.m.s. between terminals.
Output 1:
Continuous blowdown valve closes, relay contact closed
Output 2:
Continuous blowdown valve opens, relay contact closed
Output 3:
Max. limit exceeded, relay contact open
