Digi DS-425 Service Manual

3.8. Set-Point Alarm Function This function has two methods: Filling and Weight Check Method. 3.8.1. Filling Method Operator fills the item on the platter up to the target weight range. The target range is determined by 2-set-point (set-point 2 and set-point 3) and continuously fast alarm will be alert. So operator can know the weight is within the target-weight range. Set point 1 and set point 2 may be programmed as a fine adjustment range. The intermediate alarm notes to operator the weight is closed to target weight. (Near mini. Target) ...

e.g.) With Header code and weight stability code Net weight =-1,2340 Tare weight = 0,450 and weight is stable Null CR 0 - 0 1 , 2 3 0 CR 4 0 0 0 , 4 5 0 CR LF Note 1): The data format consists of (header code), minus/plus sign, numeric data and decimal point. If weight data is minus, -(2DH) is added after header data. If weight is positive data, 0(30H) is output. Note2): The data is aligned from right side. Note3): When weight is over the capacity, the following data is output: 0OV00000CR4???????CRLF (With Header Code) Note4): By specification setting, the decim ...

4.4.3. External Command Data will be output when DS-425 receives the command (ACK 06H) form PC. PC send a data request signal ACK to DS-425 side, then DS-425 transmits the weight data to PC after received the request signal, the weight data will be transferred immediately or hold the command till weight stable. If weight cannot be stable within the certain interval (set by specification), DS-425 will transmit NAK (15H) to PC. Note: If ACK signal is sent to DS-425 during digital tare or re-zero operation, NAK signal will be sent to PC. PC Side ...
