If a YS1360, YS136, YS1500, YS150, YS1700, or YS170 instruments fails, the YS110 Standby Manual Station can be used to output a 4 to 20 mA signal to the control valve actuator instead of the instruments. This standby manual station can be connected to YS1360, YS136, YS1500, YS150, YS1700, or YS170 instruments by swinging up the front display, then the instrument can be exchanged (the output is back up by the YS110), YS110 is battery operated; it can also be plugged into the instrument case and operated off the system power supply.
YS1000 Series instruments can accept ONE direct input when a signal conditioning option is specified. The direct input replaces one of the non-isolated 4 to 20mADC (using a 250Ω shunt resistor) or 1 to 5VDC inputs. YS1700 can accept five analog inputs. YS1500 can accept four and YS1310, YS1350, YS1360 can accept two analog inputs. In all cases, one input can be signal conditioned.
The YSS1000 setting software (hereinafter referred to as the YSS1000) is package software to configure the functions of the YS1000 series (hereinafter referred to as the YS1000) devices. Writing and reading of parameters and user programs of the YS1000, and PID tuning and monitoring of user programs can be performed through the use of communication.
