triggered the respective relay settings. The rightmost character will indicate RELAY 1 if the display is pH or RELAY 3 if the display is ORP. The leftmost character will indicate RELAY2 if the display is pH or RELAY 4 If the display is ORP. If the display is ORP the annunciators will only indicate the unit selected at the RELAY/mA option in the ORP CALIBRATION . - Page 9 1. Connect the AC line to the rear of the instrument. The model 6309 POT can be used with 115 or 230VAC 50/60 Hz. Power consumption is 6 watts. Make sure the EARTH connector is connected to the earth lead of the AC power line.

b. USER SETTING You will only see this page if the unit is not password locked. This page is just a WARNING, informing that all relays and analog output are frozen, and that you can calibrate and change the settings. NOTE: FROZEN MEANS ALL THE RELAYS AND THE ANALOG OUT WILL MAINTAIN THEIR LAST STATE UNTIL THE USER RETURNS TO MAIN DISPLAY MODE. -

ID/Address for unit. connecting multiple model 6309PDTF or other Jenco models for logging purposes then this ID/Address must be unique for each connected unit. This ID/Address is the same address that must be used by the PC program to communicate with this unit. -
Page 21: Controlling The Relays
V. CONTROLLING THE RELAYS A. ISOLATION VOLTAGE The maximum isolation voltage of the relay output contacts is 1500 VDC. The voltage differential between the relay output contacts and the load should not exceed 1500 VDC. B. OUTPUT LOAD The current through the relay output contacts should not exceed 5 Amp at 115 VAC and 2.5 Amp at 230 VAC in order not to cause permanent damage to the relay contacts. -
Page 22: Ph Relays
If the relay action is set to LOW and the hysteresis mode is EDGE, the relay will turn ON at [(RELAY SET POINT)], and will turn OFF at [RELAY SET POINT+ (hysteresis value)]. CAUTION : Setting any hysteresis value to zero may cause jitter and possibly damage the relay(s). -
Page 23: Orp Relays
E. ORP RELAYS There are two independent relay channels for the ORP display. (see figure 1.). The hysteresis mode (center or edge, see figure 1.) and hysteresis value will be used by all ORP relays. The action of the ORP relays are dependent on set point, relay action (HIGH or LOW), hysteresis mode (Center or Edge) , hysteresis value and the current ORP display. -

D. ORP LINEAR (mA) OUTPUT The analog output will produce a linear analog output if the user selects this option (see figure 2). The analog output will be dependent on the ORP_4 mA setting, ORP_20 mA setting and the current ORP (ABS or REL) display. The ORP LINEAR output is based on the following equation: = 4mA+(16mA)*(D - ORP(4)) /(ORP(20) - ORP(4)) -
