2.2.16

Output 1 Power Limit

This parameter is used to limit the power level of Output 1 and may be used to

protect the process being controlled. If no protection is required, this parameter

may be set to 100%. IThis parameter is not applicable if Proportional Band 1 is set

to 0.

2.2.17

Output 1 Cycle Time

The cycle time value required is dependent upon the process being controlled

and the type of output being used for Output 1. For a Relay Output, the cycle

time should be as large as possible (whilst remaining compatible with the process

control requirements) in order to maximise relay life. For an SSR Output, the cycle

time may have a lower value (and thus satisfy the requirements of a fast-changing

process variable e.g. flow or pressure). This parameter is not applicable if

Proportional Band 1 is set to 0 or if Output 1 is a DC linear output..

2.2.18

Output 2 Cycle Time

The cycle time value required is dependent upon the process being controlled

and the type of output being used for Output 2. For a Relay Output, the cycle

time should be as large as possible (whilst remaining compatible with the process

control requirements) in order to maximise relay life. For an SSR Output, the cycle

time may have a lower value (and thus satisfy the requirements of a fast-changing

process variable e.g. flow or pressure). This parameter is not applicable if

Proportional Band 1 or Proportional Band 2 is set to 0 or if Output 2 is a DC linear

output.

2.2.19

Process High Alarm 1 Value

This parameter, applicable only when Alarm 1 is selected to be a Process High

alarm, defines the process variable value at or above which Alarm 1 will be

active. The operation of a process high alarm is illustrated in Figure 2-3.

2.2.20

Process Low Alarm 1 Value

This parameter, applicable only when Alarm 1 is selected to be a Process Low

alarm, defines the process variable value at or below which Alarm 1 will be

active. The operation of a process low alarm is illustrated in Figure 2-3.

2.2.21

Band Alarm 1 Value

This parameter, applicable only if Alarm 1 is selected to be a Band Alarm, defines

a band of process variable values, centred on the setpoint value. If the process

variable value is outside this band, the alarm will be active. The operation of a

band alarm is illustrated in Figure 2-3.
