PRODUCT TERMINALS WIRING DESCRIPTION

1  ST48S/ZN48S/ZN72S Single Set Dual Digital Display 4-Digit Delay Timer

Terminals Explanations
Relay contact terminals: As normal close as normal open

COM is for public terminal; PAU is for pause, RST is for reset.
In normal working situation, should connect pause(PAU)and public (COM)terminals, then the delay stops; disconnect them, time delay continues. This function can de use as a time totalize.
In normal working situation, put through reset(RST)and public (COM)terminals, the delay timer recovers to its initial starte; Disconnect reset(RST)and public (COM)terminals, delay timer starts to work again.
CNT terminal,U0 terminal is not available
     Relay Operation modeIt has six types; please refer toRelay Operation Modefor details

ST48SS/ZN48SS/ZN72SS Double Set Dual Digital Display 4-Digit Delay TimerIntelligent Twin Delay Timer
     Terminals Explanations

Relay contact terminals: As normal close as normal open

COM is for public terminal; PAU is for pause, RST is for reset
.In normal working situation, should connect pause(PAU) and public (COM) terminals, the time delay stops; disconnect them, time delay continues.
In normal working situation, put through reset(RST) and public (COM) terminals. The delay timer recovers to its initial release time (I, e, top four LED nixie tubes display the initial value of the release time, bottom four LED nixie tubes display the set value of release time). Disconnect reset(RST) and public(COM) terminals, daily timer starts to work from the initial release time.
CNT terminalU0 terminal is not availavle
     There are mode 1 and mode 2; please refer to Relay Operation Modefor details

ST48L/ZN48L/ZN72L Single Set 8-Digtal Display Time Totalize
     Product Terminals Wiring Description

Relay contact terminals: As normal close as normal open

COM is for public terminal; PAU is for pauseDuring normal working condition, should connect pause(PAU) and public(COM) terminals, then totalizing stops; disconnect them, totalizing continues.
RST is for reset In normal working situation put through resetRST and public(COM) terminals (for 8 seconds)the totalize recovers to its initial state; Disconnect them ,the totalize will resume totalizing from the beginning (same as the front panel reset key function)
CNT terminalU0 Terminal is not available.
     Operation ModeIt has six types: please refer to Relay Operation Mode for details

ST48J/ZN48J/ZN72J Single Set Reversible Digital Display Counter
     Terminals Explanations

Relay contact terminals: As normal close as normal open

COM is for public terminal; PAU is for counter node selection, should connect pause (PAU) and public(COM) terminals, the counter is in reverse mode, the vice versa.
RST is for reset, put through reset(RST) and public (COM) terminals, the counter recovers to its initial state; Disconnect them the counter will resume working from the beginning
CNT is for counting input terminalSwitching value and electrical level pulse input signals are compatible.
The Switching Value is that the input signals produced by relay contacts, photoelectric geminate transistors etc.
Electric level pulse: Low level:-30V--+0.6V;High Level +4V--+30V input pulse maximum low level:0.6V; Input pulse minimum high level; 4V(Please refer to V. Wiring Sketch for details).
     Operation ModeIt has three typesMode 3 and Mode 5; please refer toRelay Operation Mode for details
