Important Information Setpoints are entered in values according to the function selected. Level - entered in Display Units or % of span as referenced to Empty Level. Rate of Change - entered in Display Units per minute or % of span per minute. For an alarm on a increasing level enter setpoints as a positive value, for an alarm on a decreasing level enter setpoints as a negative value. Temperature - entered in ºC. See the appropriate alarm function, table (P211, 221, 231) for further information. * To set figures in % press the hot key to show and enter % figure relative to empty level. Page 98
Pumps P210, 220, 230, 240, 250 = 2 (Pump) When a relay is being used for a pump function, the second parameter determines the pump duty that will be used to determine the operating cycle. P211, P221, P231, P241, P251 - Relay Function, This parameter defines which pump duty the relay should respond to as follows. Pump Duty Description 0= Off (Default) Relay is always de-energised. 1= Fixed duty assist All pumps are used to assist each other (run at the same time) and each pump has its own setpoints. (P213, 223, 233, 243, 253 & P214, 224, 234, 244, 254). 2= Fixed duty backup If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped and another pump shall take over. Each pump has its own setpoints. (P213, 223, 233, 243, 253 & P214, 224, 234, 244, 254). 3= Alternate duty assist All pumps are used to assist each other (run at the same time). Each pump has its own setpoints, (P213, 223, 233, 243, 253 & P214, 224, 234, 244, 254) but each time all pumps have stopped, the setpoints are sequentially rotated between the pumps to ensure equal pump use. 4= Alternate duty backup If a pump fails to meet the demand (due to malfunction, intake blockage etc.), then it is stopped and another pump shall take over. Each pump has its own setpoints, (P213, 223, 233, 243, 253 & P214, 224, 234, 244, 254) but each time all pumps have stopped, then the setpoints are sequentially rotated between the pumps to ensure equal pump use.
