General to measure the hydrostatic pressure. The pressure transmitter transmits an electrical signal proportional to the pressure, resting on the pressure transmitters membrane. The pressure transmitter is connected to the amplifier, where the signal is used for level indication, for limits for start-, stop signals and alarms, as well as for the level proportional 0-20/4-20 mA output signal. Thank you for choosing MJK Pump Controller 704.
Operation of pump controller P2 RESET TIME-COUNTER? YES: ENTER NO:MENU The keys under the display give access to the functions used in the daily operation. The MENU key gives access to programming of the pump controller. The programming can be locked separately with an access code i.e. a code must be keyed in, in order to get access to the programming menus.
Programming of pump controller level in menu 6.6.3. LEVEL 1 When function F0 shows in the display press the MENU key for access to the programming menus (if code is not applied, see menu 3.3). Change between the main menus by repeatedly pressing the MENU key. Press ENTER to change to sub menus. Make choices and adjustments in the sub menus with the arrow keys and confirm with ENTER. SET 1.90 RESET 1.70 When adjusting a level, press one of the arrow keys, consequently the setting will flash.
4.1 Select unit measurement 5.5 Key in elevation 5.6 Sensor level Select unit flow For ultrasonic measuring systems the sensor elevation above the zero point is keyed in. Use the arrow keys for this setting. Double arrow changes the value before the comma, single arrow changes the value after the comma. m3/h, l/s, MGD, CFS, G/mi 5.7 Max level The resolution of measured flow will be adjusted to the accuracy of flow measurement possible with the pump controller.
6.4 Relay operating / not operating 6.7.4 Level not in use / in use 6.5 Relay controlling / alarm 6.8 Relay delay Choose the relay function for the output, (Normally Open) or (Normally Closed). 7.0 mA output programming 6.6.3 7.1 mA output 0-20mA / 4-20mA 7.2 mA output 4-20mA / 20-4 mA 7.3 mA output 4 mA = (elevation) 7.4 mA output 20 mA = (elevation) 8.0 Pump flow programming Choose whether to have the relay operating or not operating.
1.All start / stop levels must be outside the interval in which calculation takes place. The flow calculation can only be carried out between the lowest set start level and the highest set stop level with a margin of sensor span/200. 2.The connected pumps must regularly run on their own to obtain reliable flow measuring. If the above mentioned conditions are not present the following message will appear in the display, when entering menu 8.
Mounting Pressure Transmitter When measuring in a well, it is advantageous to mount the transmitter in a tube, fastening it at the top of the tube by means of the fittings supplied. This mounting facilitates subsequent cleaning and inspection. Min. table value +100% Min. 25in (30kHz) 45o Sensor mounted in tube for scum protection. Sensor mounted near the top of a closed container.
Electrical Connection Electrical connection of the pump controller for hydrostatical and ultrasonic measuring systems respectively. Hydrostatic Measuring System Supply Relay 1-4 0-20/4-20mA Pressure transmitter Ultrasonic Measuring System Supply Relay 1-4 0-20/4-20mA Connection Box for transmitters Connection box 202922 is used for outdoor connections of cables from the pressure transmitter. The box is made of ABS plastic, and the housing meets IP65.
Changing the EPROM If the EPROM with the pump control program is to be replaced, you must follow these instructions: Dimensions Pressure transmitter Amplifier Bracket 1.Turn off the pump controller 2.Turn off all pumps, to ensure that no accidents will occur when the pump controller is turned back on. This can be accomplished by disconnecting the pumps at the terminals on the pump controller. 3.Remove the top lid 4.Remove the EPROM (IC5) from the socket, be very careful not to ruin the IC.
