Siemens 200 instruction manual Range Calibration P650 to P654, P645 Relay Duration MR

This parameter is relevant only if Operation is set to OCM (P001 = 6).

Enter the exponent (Z) for the mantissa (Y) in the formula:

Flow Sampler Increment = Y x 10Z Flow units.

P645 Relay Duration [MR 200]

Use this feature (if desired) to adjust the minimum contact closure duration of a relay set as a totalizer, flow sampler, time (control), or aeration (P111 = 40, 41, 60 or 62)

Primary Index	Global
Values	Range: 0.1 to 1024
	Preset = 0.2 (sec)
Related	•	P111 Relay Control Function

Enter minimum contact closure duration (in seconds) required by the device connected.

For the flow sampler function this value is used for both the ON time of the relay and the OFF time between contacts.

P645 on time

relay contact closed

P645 OFF time

relay contact open

Range Calibration (P650 to P654)

There are two types of calibration possible:

Offset: Adjusts the measurements by a fixed amount.

Sound Velocity: Adjusts speed of sound and changes the measurement calculations.

Do Offset calibration at any steady level unless a Sound Velocity calibration is also done. If both calibrations are done then do Offset at a known high level and Sound Velocity at a known low level.
