Cycle Time, Output 1A or 1B

Select the time, in seconds, of a complete on/off cycle.

[Ct1A] This prompt appears only if [`In1] (Input Menu) is not set to a

process, [CntL] (Global Menu) is not set to [CSCd] and [Pb1A] is set high-

er than [```0].

Proportional Band, Output 2A or 2B

Select the proportional band for PID output 2. If set to [```0] it func-

tions as an on/off control, and the switching differential is determined by

the [HYS2] value (Output Menu). Decimal precision is determined by the

[`dEC1] or [`dEC2] setting (Input Menu).

[Pb2A] This prompt appears only if [CntL] (Global Menu) is not set to

[CSCd] and if [`Ot2] (Output Menu) is set to [``Ht] or [``CL] or if [ALg0]

(Global Menu) is set to [dUPL].
